Question

Find the area of the circle. Round your answer to two decimal places, if necessary.​

Answer 1

379.94 in.²

Explanation:

To find the area of a circle, multiply the radius by itself twice, then multiply the product by pi.

`a=\pi r^2`

In the image, the diameter is shown.

To find the radius of a circle, divide the diameter by 2.

`22/2=11`

The radius of this circle is 11 inches.

Next, multiply the radius by itself twice.

`11*11=121`

Lastly, multiply the product by pi (3.14).

`121*3.14=379.94`

Therefore, the area of this circle is 379.94 inches squared.
