Formula to calculate sphere area, spherical volume

The spherical surface is a locus of points fixed by a fixed point O of a constant r in 3-dimensional space. Point O is called the center and the distance r is called the radius of the sphere.

The sphere , also known as the sphere, represents the inner part of a sphere.

In fact, we encounter a lot of spherical objects in our daily life, most familiar with all kinds of balls (football, volleyball, basketball .), or our earth is in the form of a sphere. . The lessons of the area or volume of spheres are also applied from the lower and upper secondary levels and also in the program of studying algorithms for later.
