To play a game, all the children in class stand in a circle, the diameter of the circle is 15 feet. what is the circumference of the circle to the nearest tenth of a foot? use 3.14 for the value of pi

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
