Henry is a ringmaster for the circus. He stands inside a circular circus ring that has a circumference of 3π meters. What is the area of the circus ring in square meters?
Circumference = 2pi * r
3pi = 2pi r divide away pi
3 = 2 r
(3/2) = r = 1.5 m
Area = pi ( r^2) = pi (1.5)^2 = 2.25 pi m^2 ≈ 7.07 m^2
