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

[tex]A = \pi * r ^ 2[/tex]

Where:

A: It is the radius of the circle

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

Substituting we have:

[tex]A = \pi * (8) ^ 2\\A = \pi * 64\\A = (3.14) (64)\\A = 200.96[/tex]

Thus, the area of the circle is [tex]200.96 \ in ^ 2[/tex]

Answer:

[tex]200.96 \ in ^ 2[/tex]
