Radius of Circle Calculation

Radius of a circle is the distance from the center of the circle to the point on the circle. It is represented using the letter r.

Learn here on how to calculate the radius of a circle given the diameter.

Radius of Circle r = Diameter (D) / 2

Let us consider an example to find the radius of the circle whose diameter is 8.
r = D / 2
= 8/2
= 4
