### What is Meant by Surface Area of a Sphere?

In mathematics, the sphere is a three-dimensional round-shaped solid figure. The solid shape sphere is obtained from the rotation of the two-dimensional shape figure called a circle. The sphere is defined as the set of points that are equidistant from the centre point in a three-dimensional area. The distance between the boundary and the centre point of the sphere is called the radius “r’. The formula to calculate the surface area of a sphere is given by:

The Surface area of a Sphere =  4πr2 Square units
