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

A circle is a collection of points on a two-dimensional plane, which are equidistant from the center point 'O'.

## Answer: The diameter can be calculated by dividing the value of the circumference of a circle by pi (or 22/7).

Let's find the diameter of a circle using the circumference of a circle.

**Explanation:**

Pi is the ratio of the circumference of a circle to its diameter. The value of pi is approximately equal to 3.14 or 22/7

So, pi = circumference / diameter

diameter = circumference / pi

For example, if the circumfernce of a circle is 110 cm then the diameter = 110 / pi = 110/ (22/7) = (110 × 7) / 22 = (5 × 7) = 35 cm.
