Given that we know the diameter and gather we know pipe 3.14, we can use the formula C = pi*D where d is the diameter and C is circumference of the circle. Plug in what we know for the variables and then solve.
C = 3.14*12
C = 37.68
Rounding our answer, we get 37.7, so our answer is 37.7 ft. Hope this helps
