Danny Walls · Answer 1

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

Ryker Andrews · Answer 2

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!
