User: If the area of a circle is 706.5, what is the circumference ?

Weegy: Area = 2 (3.14) r^2 Circumference = 2(3.14)r find radius first 706= 2(3.14) r^2 706= 6.28r^2 square root whole equation ->706/6.28 r= 10.60 C=2(3.14)X 10.60 C=66.60

Circle Area = Pi*r^2 = 706.5
r^2 = 706.5/3.14 = 225
r = sqrt 225 = 15
Circe Circumference = 2*Pi*r = 2*3.14*15 = 94.2
