Answer:

A. 8

Explanation:

When finding the radius of a circle given area we have to remember the following formulas


A=\pi *r^(2) and
r^2=(A)/(\pi ) or
r=\sqrt{(A)/(\pi ) }

So using either
r^2=(A)/(\pi ) or
r=\sqrt{(A)/(\pi ) } we fill out the following


r^2=(64\pi )/(\pi )
r=\sqrt{(64\pi )/(\pi ) } both would equal 8

The image below explains how we get 8
