Answer 1

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
