All circles have circumferences of 2πr.
In this case radius = r = 12
then circumference = 2(3.14)(12) = 75.36 ft

Somehow, when learning formulas, many teachers, tutors and students forget definitions:
The definition of Pi (∏) is the ratio of the circumference of a circle to its diameter. That is, ∏ = C/d
That makes the circumference, C=∏d = 2∏r
