Find the area of the circle. Round your answer the nearest whole number, if necessary.

mina [271]

Answer:

The area of the circle is 314 in^2.

Step-by-step explanation:

10 inches is the radius.

The formula for the area of a circle is pi times radius squared.

So your equation would be: $A=\pi (10)^2$

10^2 = 100

Then you do $\pi$ or 3.14 times 10 = 314.1592654 or just 314.

Hope I helped ya.
