Find the area of the circle. Round your answer to two decimal places, if necessary.​
nirvana33 [79]

Answer:

379.94 in.²

Step-by-step 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.
