# How to find the diameter of a circle with the circumference?

In a circle the length of the boundary is called circumference of the circle.

## Answer: The diameter can be calculated as circumference/pi.

The diameter of a circle is a straight line joining a point from one end of the circle to a point on the other end of the circle, passing through the center.

## Explanation:

In any circle the ratio of its circumference to its diameter is always same regardless of their size.

This ratio is called pi (π).

Circumference of a circle is given by pi × diameter.
