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

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

## Answer: The radius of a circle using the circumference can be found by the formula Radius = Circumference / 2π

Let's calculate the radius of a circle when the circumference of a circle is given.

**Explanation:**

The distance from the center point to any endpoint on the circle is called the radius of a circle. It is denoted by 'r.'

The formula to find the circumference of a circle is given by 2 π r.

Thus, when the circumference is known, the formula for the radius is: Radius = Circumference / 2π

For example, if the circumference is 44cm, then the radius = 44 / 2π = 44 / (2 × 22/7) = 7cm

### Therefore, Radius = Circumference / 2π is the formula to find the radius of a circle using the circumference.
