HELP ASAP PLS the area of the circle is 64 pi square cm what is the radius of the circle in cm

Answer 1

8cm

Step-by-step explanation:

let radius of circle be r

area of circle = 64π cm^2

π×r^2=64π

r^2=64 (cancel out π from both side)

r=√64 ( square root both side to remove the power from r)

r=8 cm
