### What is Meant by Sphere?

In mathematics, a sphere is a closed three-dimensional round shaped figure. The sphere is the three-dimensional form of the 2D shape circle. In the three dimensional space, the set of all the points which are equidistant from the centre C. The distance between the centre point and the surface of the sphere is called the radius “r”. The formula to calculate surface area and the volume of the sphere is given by the formula

The surface area of sphere = 4πr2 square units

The volume of sphere = (4/3) πr3 cubic units
