The area of a circle is 17 square meters. What is its circumference?
------------
A = pi*r^2
r = sqrt(A/pi)
C = 2pi*r
C = 2pi*sqrt(A/pi)
C = 2*sqrt(A*pi)
C = 2*sqrt(17pi)
C = ~14.616 meters
-------------
Or, you can solve for r, then C
A = pi*r^2 sq meters
r = sqrt(A/pi)
r =~ 2.3262 meters
C = 2*pi*r
C = ~14.616 meters
