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
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
