How to find the radius of a sphere with the circumference?

A sphere is a three dimensional figure that has no vertices, no edges and only one curved face.

Answer: The radius of a sphere with the circumference is C/ 2π.

Let us find the radius.

Explanation:

Let the  Circumference of the sphere = C and radius = r

We know that,

Circumference of a circle = 2πr

⇒ C = 2πr

⇒ r = C / 2π

Thus, the radius of the sphere with circumference C is C/ 2π.
