The sphere surface area is the sum of the area of the surface of the sphere. It is the amount of two-dimensional space held by the sphere.
By using the following formula you can obtain the surface area of a sphere:
Surface area = 4πr^2
In which, r is the sphere radius (the distance between the center of the sphere and the surface).
For instance, take a sphere with a radius of 5 inches. The sphere's surface area would be:
Surface area = 4π(5^2)
= 4π(25)
= 100π
Thus, the surface area of the sphere is about 100π square inches.
It is necessary to remember that the surface area of a sphere does not cover the volume of the sphere (the amount of three-dimensional space inside the sphere). You can obtain the volume of a sphere by using a different formula.
