How much fencing is needed to enclose a circular tulip garden whose area is 16(pie) square meters?

OpenStudy (merchandize):

A = πr² 16π = πr² Divide both sides by π 16 = r² r = 4 The amount of fence needed is equal to the circumference of the circle. C = 2πr, given r = 4 C = 2π(4) = 8π I hope that helps, good luck.
