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

 

So

 

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
