The area of circle Z is 64Pi ft2. Circle Z is shown. Radius D has length r. R = StartRoot StartFraction Area Over pi EndFraction EndRoot What is the value of r? r = 4 ft r = 8 ft r = 16 ft r = 32 ft

r = 8 ft

Step-by-step explanation:

Area of a circle => πr²

We are told in the question that:

The area of circle Z is 64Pi ft²

= 64π ft²

What is the value of r

We equate

πr² = 64 π

r² = 64 π/π

r² = 64

We square root both sides.

√r² = √64

r =>8 ft

      B... r= 8 ft
