## Sphere & its Formulas

The following mathematical formulas are used in this sphere calculator to find the surface area & volume of a sphere

### Solved Example

The below solved example problem may be useful to understand how the values are being used in the mathematical formulas to find the surface area & volume of a sphere.

Example Problem :
Find the surface area & volume of a sphere having the radius of 9 cm?

Solution :
The given values
radius r = 9 cm

Step by step calculation
formula to find surface area = 4 π r2
substitute the values
= 4 x π x 92
= 1018.28 cm2

formula to find volume = (4/3) π r3
substitute the values
= (4/3) x π x 93
= 3054.85 cm3
