Question

The circumference of a circle is three pi inches. What is the area of the circle?

Answer 1

Explanation:

C=pi*3 Given

Generally C = 2*pi*r so we need to solve for r

3 pi = 2*pi * r Divide by 2pi

3 pi/2pi = r

r = 1.5

Area = pi r^2

Area = pi * 1.5^2

Area = 2.25 pi

If you need a 1 number answer

Area = 7.065
