Diameter from Circumference
Diameter from Circumference
\[d = \frac{C}{\pi}\]
Variables
d = diameter (m)
C = circumference (m)
Description
What is this formula?
This formula calculates the diameter of a circle from its circumference. The diameter is the straight-line distance passing through the center of the circle.
When to use it
Use this formula when the circumference of a circle is known and the diameter needs to be determined.
Example
If the circumference is 31.416 m:
d = 31.416 / π = 10 m
