Area of a Sphere

Description

A sphere is a perfectly round geometrical and circular object in three-dimensional space that resembles the shape of a completely round ball. A sphere is defined mathematically as the set of points that are all the same distance from a given point in three-dimensional space. This distance is the radius of the sphere, and the given point is the center of the sphere.
Area is the quantity that expresses the extent of a two-dimensional figure or shape, or planar lamina, in the plane. The area of a sphere can be calculated by its radius.
