# Sphere Calc : Find A

A Sphere is a perfectly round geometric three-dimensional object. Planets, Orange, Ball are some of the examples of a sphere. The distance from any point on the sphere's surface to the center is always same. Archimedes has derived the formula for the surface of the sphere. Use this online Surface Area of a Sphere Calculator to find the value of surface area and volume of the sphere. In this Sphere Calc, find 'A' by providing radius value as input.

#### Formula:

Surface Area(A) = 4 × π × r^{2}
**Where,**
r = Radius
### Example:

Find surface area(A) of sphere having radius as 7cm?

#### Area of a Sphere

= 4 × π × 7^{2}

= 615.7522cm^{2}
