Can't get this wrong ! if the area of a circle measures 9π cm2, what is the circumference of the circle in terms of π? a) 3π cm b) 6π cm c) 9/4 π cm d) 9/2 π cm

A = π*r^2 . . . . . . . . . . . . formula for area
9 π cm^2 = π*r^2 . . . . . substitute the given information
9 cm^2 = r^2 . . . . . . . . divide by pi
3 cm = r . . . . . . . . . . . . . take the square root

C = 2π*r . . . . . . . . . . . . . formula for circumference
C = 2π(3 cm) . . . . . . . . substitute for r
C = 6π cm . . . . . . . . . . . matches selection B
