Step 1) Use the area formula to find the length of the radius
A = (3.14 x r^2) / 4
3.14 = (3.14 x r^2) / 4
12.56 = 3.14r^2
r^2 = 4
r = 2 feet
Step 2) Use the perimeter formula to find the perimeter
C = ((pi x 2r) / 4) + 2r
C = ((3.14 x 4) / 4) + 4
C = (12.56 / 4) + 4
C = 3.14 + 4
C = 7.14 feet
Hope this helps! :)
