Answer: 56.52 feet</h3>
=======================================================
Work Shown:
d = diameter = 18 ft
pi = 3.14 approximately
C = circumference
C = pi*d
C = 3.14*18
C = 56.52
The distance around the circle's edge (aka perimeter) is about 56.52 feet
The result is approximate since pi = 3.14 is approximate.
