Sphere
A sphere is a solid, all points of that are equidistant from a fixed point, the center, as shown in Figure.
The volume of a sphere is computed using the subsequent formula:
V =4/3 πr3
The surface area of a sphere is computed using the subsequent formula:
SA = 4 πr2
Surface area of the sphere is expressed in square units, and the volume of a sphere is expressed in cubic units.
