Area+=+pi%2Ar%5E2
+60+=+pi%2Ar%5E2
divide each side by pi
+60%2Fpi=r%5E2
take the square root of each side
+sqrt%2860%2Fpi%29=r
The circumference, and thus the amount of fence = pi%2AD or pi%2A2r
pi%2A2%28sqrt%2860%2Fpi%29%29
sqrt%2860%2Fpi%29=4.3702
so pi%2A2%28sqrt%2860%2Fpi%29%29 = pi%2A2%284.3702%29
pi%2A2%284.3702%29 = 27.4588 = 27.459 meters
