Geometry Tutorials: How to calculate the volume of a sphere
To calculate the volume of a sphere we need to make use of a formula which will make little to no sense to an untrained mathematical eye. Indeed the main components are Pi and the radius. As with circle surface area calculations we will multiply these two elements by one another, but unlike with the surface element of a circle, we will not just require the radius squared, but indeed the radius as a cube:
As you have probably noticed viewing the above formula Pi times radius cubed are not the only components needed to calculate the volume of a sphere. Indeed the second task is to multiply the result times four thirds.
If you carry out the above formula correctly you will end up with the volume of your sphere. Note that you will need to apply your cubic units of measurement once you have obtained the result.
