## How to Find Radius Calculator?

Radius can also be defined as the length of the line segment from the center of a circle to a point on the circumference of the circle. The length of the radius is equal to half the length of the diameter.

**Radius = Diameter / 2**

**Solved Example:**

Find radius if the diameter is 7 units.

**Solution:**

Given diameter = 7 units

We know that radius = diameter / 2

= (7 / 2) units

= 3.5 units

Therefore, radius = 3.5 units.

Similarly, you can use the calculator to find the radius for the following:

- Diameter = 10 units
- Diameter = 15 units
