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

If the area of a circle is 706.5, what is the circumference ?
"is 94.2."
Developing
r = sqr(A/pi)
r = sqr(706.5/3.14)
r = 15
diameter = r * 2
d = 30
circumference = d * pi
c = 30 * 3.14
c = 94.2
