The circumference of a circle
is the perimeter of the circle. This is the measurement of
the total distance around the circle. |
| The most essential part to
finding the circumference of a circle (next to the circle itself)
is the radius. This is the distance from the center to any
point on the circle itself. |

 |
Another essential part to finding the circumference
of a circle is the value of pi. Pi is the value of the
circumference divided by the radius doubled. This value is
3.141592654 |
| These elements are put into a formula where 2 times
the radius times pi equals the circumference. |
 |
 |
Example: Let the radius equal 5
centimeters. We take this value and multiply it by 2 and
pi. This gives us 10 pi centimeters. |
