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:

  1. First, determine the total circumference. 
    • The total circumference is given as: 500.
  2. 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 = ?
