Question

find the area of a circle that has a circumferemce of 12pi. (use pi = 3.14)

formulas

R=radius

area of a circle = piR^2

Cricumference of circle= 2piR

Answer 1

Radius = 6  (2PiR  12/2=6)

PiR^2 = Pi 6^2

=36Pi or 113.04

Answer 2

Circumference = 2 pi R = 12 pi

Therefore Radius = 6

Area of cirle = pi R^2 = pi 6^2 =36 pi=36x3.14 =113.04
