From a visual perspective, a sphere has a three-dimensional structure that forms by rotating a disc that is circular with one of the diagonals. Let us consider an instance where spherical ball faces are painted. To paint the whole surface, the paint quantity required has to be known beforehand. Hence, the area of every face has to be known to calcu...
The surface area of a sphere formula is given by, A = 4 π r2 square units For any three-dimensional shapes, the area of the object can be categorised into three types. They are: 1. Curved Surface Area 2. Lateral Surface Area 3. Total Surface Area Curved Surface Area: The curved surface area is the area of all the curved regions of the solid. Latera...

Jun 11, 2023 · The surface area of a sphere is the entire region covered by its outer round surface. It is also the curved surface area of a sphere. Like all other surface area it is expressed in square units such as m 2, cm 2, and mm 2. We will learn how to find the surface area of a solid sphere. The equations are given below.
