Respuesta :

A = 1/4 * (pi) * d^2
A = 1/4 * (pi) * 8^2
A = 1/4 * (pi) * 64
A = 1/4(64) * (pi)
A = 64/4 * (pi)
A = 16 (pi) in^2
Your answer is 16 pi in^2

The area formula for a circle is [tex] \pi r^{2} [/tex].
So, if we know the diameter of the circle, we can divide the diameter by 2 to get r (radius).

A = [tex] \pi (8/2)^{2}[/tex] = [tex] \pi (4)^2[/tex] = 16[tex]\pi[/tex] inches squared.

Hope I could help you out!
Have a good one, and God bless you!
