What is Meant by Surface Area?

In Mathematics, the surface area is defined as the total area region that the surface of the object occupies. The surface area is generally defined for three-dimensional objects/shapes. We know that the sphere is the three-dimensional form of a circle. The distance from the centre and the point on the surface of the sphere is called radius “r”. Thus, the formula to calculate the surface area of the sphere is given as:

The Surface Area of the sphere, SA = 4πr² square units
