How to find the radius of a circle with the diameter?

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/length of the radius of a circle with the diameter = (length of diameter)/2

Let's calculate the radius of a circle when the diameter 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 radius of a circle can be found when the diameter is given by the formula:  Radius = Diameter / 2

If diameter is 10cm then the radius is 10/2 = 5cm

Thus, if the diameter is given the radius is obtained by dividing the length of diameter by 2.
