For this case we have by definition, that the area of a circle is given by:


A = \pi * r ^ 2

Where:

A: It is the radius of the circle

They tell us as data that the radius is 8 inches.

Substituting we have:


A = \pi * (8) ^ 2\\A = \pi * 64\\A = (3.14) (64)\\A = 200.96

Thus, the area of the circle is
200.96 \ in ^ 2

Answer:


200.96 \ in ^ 2
