## Hemisphere & its Formulas

The following mathematical formulas are used in this hemisphere calculator to find the surface area & volume of a hemi-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 hemisphere.

Example Problem :
Find the surface area & volume of a hemisphere having the radius of 7 cm?

Solution :
The given values

Step by step calculation
formula to find surface area = 2 π r2
substitute the values
= 2 x π x 72
= 308 cm2

formula to find the volume = (2/3) π r3
substitute the values
= (2/3) x π x 73
= 718.66 cm3
