Question

Area = 64 pi in. Squared what is the radius

Answer 1

Answer:

8 inches

Step-by-step explanation:

Assuming the figure is a circle

A = pi r^2

Given the area is 64 pi

64 pi = pi r^2

Divide each side by pi

64 pi /pi = r^2 pi/pi

64 = r^2

Take the square root of each side

sqrt(64) = sqrt(r^2)

8 = r

The radius is 8 inches

Answer 2

Answer:

Step-by-step explanation:

if it is a circle.

area of circle=π r²,where r is radius of circle.

πr²=64π

r²=64=8²

r=8
