We'll also consider the provided answer choices to nail the correct answer. The main focus of our topic is calculating the area of a regular hexagon. We'll explore the properties of regular hexagons, relate the radius to the side length, determine the apothem, and finally, apply the area formula. So, let's begin, shall we?
Understanding Regular Hexagons
First things first, what exactly is a regular hexagon? Well, it's a six-sided polygon where all the sides are equal in length, and all the interior angles are equal. Think of a perfectly symmetrical honeycomb cell – that's a great visual of a regular hexagon. One of the key features of a regular hexagon is that it can be divided into six congruent equilateral triangles. These triangles are formed by connecting the center of the hexagon to each of its vertices (corners). The radius of the hexagon is the distance from the center to any vertex, which is also the length of the side of each equilateral triangle. This means each of the six triangles has sides equal to the radius, in our case, 20 inches. This fundamental understanding is important. The core concept we need to understand is the relationship between the hexagon's radius and the sides of the equilateral triangles that make it up. This concept is crucial for solving the area problem. Now, let's apply this knowledge to our question. Let's break this down so you are able to understand. When calculating the area of a regular hexagon, the starting point is always to be familiar with its structure. This will enable us to apply the formula. We'll move towards this goal with a clear-cut approach to the problem.
To recap, a regular hexagon has equal sides and equal angles. It can be divided into six equilateral triangles, and its radius is the same as the side length of those triangles. Keep this idea in your mind. This is super important for this problem. Now, let's proceed to solve our question. Let's try to relate the information we have. Always keep in mind that we can divide the hexagon into 6 equilateral triangles. This is a very important clue. In the upcoming sections, we will see how we can apply the provided information to our main question. We will figure out the area of our regular hexagon. Always try to visualize the problem, and this visualization helps in understanding the geometry. This ability will help you solve most problems in geometry. Now, let's use this knowledge to figure out how we solve our question.
Connecting Radius and Side Length
Now, the radius of our hexagon is given as 20 inches. As we've seen, the radius is also the length of the side of each of those six equilateral triangles. This makes our lives easier. Therefore, each side of the hexagon is 20 inches long. This helps us find the area. In this case, since the radius is 20 inches, the side of the hexagon is also 20 inches. Now, we need the apothem, but how to find it? That is the next step of our plan. Understanding this relationship is very important. Without it, we cannot go further. The side lengths are equal to the radius, which is 20 inches. Therefore, the hexagon is formed of six equilateral triangles. Now, what is the area of the triangle? We will find that, and then we will be able to find the area of the hexagon. The hexagon is made of triangles, and we can find the area of a single triangle, and the area of the hexagon is 6 times the area of one triangle. This way of thinking helps us solve this. Let's start our calculations. Remember that the key concept here is that the radius of the hexagon is the same as the side length of the hexagon. With this connection, the problem becomes more accessible.
So, how do we calculate the area of each of those triangles? We will use the triangle formula. We know the side, but we also need the height. But how do we find the area of an equilateral triangle? That brings us to the apothem. The apothem is the distance from the center of the hexagon to the midpoint of any side. It's also the height of each of the equilateral triangles. The apothem divides each equilateral triangle into two 30-60-90 right triangles. Using some trigonometry or the Pythagorean theorem, we can find the apothem. The apothem helps us find the area of a single equilateral triangle. Since we have 6 triangles, we multiply the area of the single triangle by 6. Now, let's do this in detail.
Calculating the Apothem
Here's where things get interesting. We need to find the apothem, which is the height of those equilateral triangles. For a regular hexagon, you can calculate the apothem (a) using the formula: a = (side length / 2) * √3. Given that the side length is 20 inches, the apothem is (20 / 2) * √3 = 10√3 inches. To make it easier to use, we can approximate √3 as 1.732, which means the apothem is approximately 10 * 1.732 = 17.32 inches. The apothem is the perpendicular distance from the center of the hexagon to the midpoint of one of its sides. This perpendicularity is important. In a regular hexagon, the apothem will bisect the interior angle of each vertex. This characteristic helps us with calculation. Now, let's focus on the calculation part. In the case of our hexagon, the side length is 20 inches. This makes the calculation of the apothem quite straightforward. With the apothem, we are able to use the area formula. This means we can find the area of a single triangle. Remember, the apothem is a crucial component in calculating the area. Using the apothem in your calculations will make it possible to get the correct answer.
The apothem is a key element in finding the area. It is used in the area formula. It is also used to derive the area of the individual triangles. Without the apothem, the calculation of the area will be impossible. So, we need to remember this concept and use it. Now, it's time to calculate the area. Let's find the area of each equilateral triangle. Remember that each equilateral triangle's area is given by 1/2 * base * height. The base is the side length. The height is the apothem. This helps us to calculate the area. This way, we can find the area of each equilateral triangle.
Determining the Area of a Single Triangle
Now we have the side length (20 inches) and the apothem (approximately 17.32 inches). The area of one triangle is (1/2) * base * height, so (1/2) * 20 inches * 17.32 inches = 173.2 square inches. That's the area of one of the six equilateral triangles. We are close to the answer! The area of one triangle is important. Since we know the area of a single triangle, we can easily calculate the area of the hexagon. So, let's go forward. We will now calculate the area of the entire hexagon. The area of a single triangle plays a key role in the final calculation. Understanding how to calculate the area of one triangle is fundamental. This is not so hard, right? This calculation is crucial to getting the final answer. Let's use this concept to find the area of our hexagon. The area of each equilateral triangle is crucial. Let's apply the triangle area formula, and we get our result.
Understanding the formula is also important. The area is 1/2 times the base multiplied by the height. The height is the apothem, and the base is the side length. So, how do we use this formula? We substitute our values in. What will we get? We will get the area of our equilateral triangle. Let's calculate the area of one equilateral triangle. This helps us to find our answer.
Calculating the Total Area of the Hexagon
Since the hexagon is made up of six identical triangles, the total area is 6 * 173.2 square inches, which equals approximately 1039.2 square inches. Let's look at the answer choices. We can see that answer choice B, 1,038 in^2 is the closest match to our calculated area. This shows us how the area of a single triangle combines to make up the whole hexagon. In the final step, we will pick our answer. Now we know that the total area is the area of 6 triangles. The area of one triangle multiplied by 6 is our total area. Now, to finalize our answer, we compare the results we calculated to the available answer choices. We need to be careful when selecting our answer.
We have found the total area of the hexagon. Now, let's consider the answer choices. The answer that matches our calculation is the one that we need. In our case, the closest match is the choice B.
