Enter the total circumference into the Reverse Circumference Calculator. The calculator will evaluate and display the diameter.

## Reverse Circumference Formula

The following formula is used to calculate the Reverse Circumference.

**D = C / pi**

- Where D is the Reverse Circumference (diameter)
- C is the total circumference

## How to Calculate Reverse Circumference?

The following example problems outline how to calculate Reverse Circumference.

Example Problem #1:

- First, determine the total circumference.
- The total circumference is given as: 500.

- Finally, calculate the Reverse Circumference using the equation above:

D = C / pi

The values given above are inserted into the equation below and the solution is calculated:

D = 500 / pi = 159.154 (diameter)

Example Problem #2:** **

For this problem, the variables required are provided below:

total circumference = 670

Test your knowledge using the equation and check your answer with the calculator above.

D = C / pi** = ?**
