## Example

## Generic Formula

**Radius**– This is the radius of the sphere which you want to calculate the volume of.

## What It Does

This formula will calculate the volume of a sphere given its radius.

## How It Works

The volume of a sphere is given by the above formula where **π** is a constant approximately equal to **3.14159265** and **r** is the radius. Excel has this constant built in as a function with no parameter inputs PI().

The POWER function will take any number and raise it to the power of any other number. POWER(Radius,3) will return the cube of the Radius. In our example, POWER(3,3) results in 27, and (4/3)*3.14159265*27 = **113.1**.
