Surface Area of a Sphere Calculator
Surface Area of a Sphere Formula: 4 * π * Radius²

Surface Area of a Sphere Definition
The Surface Area of a Sphere Calculator will calculate the surface area of any sphere if you enter in the radius of the sphere. A sphere is a perfectly round 3 dimensional object (i.e. a ball!). Enter in the radius of the sphere below to calculate the surface area of a sphere and use the formula for calculating the surface area of a sphere given below to work backwards if you have the surface area of a sphere and are trying to solve for the radius of a sphere. Also, find the Volume of a Sphere.

How to Calculate Surface Area of a Sphere
Let's be honest - sometimes the best surface area of a sphere calculator is the one that is easy to use and doesn't require us to even know what the surface area of a sphere formula is in the first place! But if you want to know the exact formula for calculating surface area of a sphere then please check out the "Formula" box above.
