Enter the circle diameter into the Circle Length Calculator. The calculator will evaluate the Circle Length.

## Circle Length Formula

The following two example problems outline the steps and information needed to calculate the Circle Length.

CL = CD * pi

- Where CL is the Circle Length ( )
- CD is the circle diameter

To calculate the circle length, multiply the circle diameter by pi.

## How to Calculate Circle Length?

The following example problems outline how to calculate Circle Length.

Example Problem #1:

- First, determine the circle diameter.
- The circle diameter is given as: 5.

- Finally, calculate the Circle Length using the equation above:

CL = CD * pi

The values provided above are inserted into the equation below and computed.

CL = 5 * pi = 15.707
