Simple instructions to find the circumference of a circle with an explanation of * Pi* to find the circumference.

These instructions are written in a simple format to quickly explain how to find the circumference of a circle and briefly explains Pi with formulas and example shown.

## Instructions

The outer part of a circle is described as its * circumference* like the example shows. That’s the distance around the entire circle. If you divide the circumference by the diameter, you get a value called

*Pi*.

* Pi* is pronounced the same as the PIE you eat. The symbol used to represent Pi doesn’t look as tasty. It appears like this symbol. It’s basically a simple way of representing the number

**3.14159265….**, but easier to just remember and use

*from now on. Pi is a constant number.*

**3.14**To find the circumference of a circle you multiply the diameter by Pi. The formula looks like this:

For example, if * d=3* feet, then you multiply 3 feet by 3.14. In this case the circumference would be 9.42 feet/ft.
