To find the circumference you must multiply the diameter by pi. In this case, multiply 15 by 3.14 and you get 47.1 feet. There you go!
The formula for circumference of a circle is: C=2PIr so the steps to solve are as follows:
1. Find the radius
a. The radius is 1/2 the diameter so you would divide 15 by 2 which equals 7.5
2. Plug in the information you already know
a. C=2(3.14)(7.5)
3. Solve for C (I used a calculator here for accuracy)
a. C= 47.1
