The radius of a circle is 36.6 miles. What is the circle's area?

Use [tex]\pi \approx 3.14[/tex] and round your answer to the nearest hundredth.

[tex]\(\square\)[/tex] square miles

Answer :

To find the area of a circle when the radius is given, we can use the formula for the area of a circle:

[tex]\[ \text{Area} = \pi \times r^2 \][/tex]

where [tex]\(\pi\)[/tex] is approximately 3.14, and [tex]\(r\)[/tex] is the radius of the circle.

Let's go through the steps to solve this problem:

1. Identify the radius: The radius of the circle is given as 36.6 miles.

2. Use the formula for the area:

[tex]\[ \text{Area} = 3.14 \times (36.6)^2 \][/tex]

3. Calculate [tex]\(r^2\)[/tex]:

[tex]\[ (36.6)^2 = 1339.56 \][/tex]

4. Multiply [tex]\(r^2\)[/tex] by [tex]\(\pi\)[/tex]:

[tex]\[ \text{Area} = 3.14 \times 1339.56 = 4206.2184 \][/tex]

5. Round the area to the nearest hundredth: The area of the circle, rounded to the nearest hundredth, is 4206.22 square miles.

So, the circle's area is approximately [tex]\(4206.22\)[/tex] square miles.
