Question

If the circumference of a circle measures 12 pi cm, what is the area of the circle in terms of pi?

Answer 1

Answer: 36*pi cm

Explanation:

Since the formula for the circumference is C=2*pi*r

12pi=2*pi*r we can divide and get r=6 cm

Then, we can use the formula for the area of a circle: Area=pi*r^2 and get Area=pi*6^2=36*pi cm.

Answer 2

Answer: 36pi cm^2

Explanation:

Circumference= 2pi r

Since circumference is 12pi

r = 12pi/2pi

r = 6cm

Area= pi r^2

= 6^2 pi

= 36pi cm square.
