How To Find The Surface Area Of A Sphere?


Let's look at the geometric characteristics of a sphere. But first, please review the definition of Surface Area Of Three-Dimensional Shapes
  • A sphere has a very unique feature, all points on the surface of the sphere are equal distance from the center of the sphere; or said another way, the distance from the center of a sphere to the surface is equal to the length of the Radius.
  • Special note, the radius of a sphere must be greater than zero.

Surface Area Of A Sphere
Surface Area = 4 × π × Radius2 =
Surface Area = 4 × π × r2 =
Surface Area = 4πr2
