Demonstration-Visualizing the Volume of a Cone and Cylinder Formula

Demonstration of the Volume of a Cone compared to the volume of an equal sized cylinder using water.

In this demonstration, you will see how the volume of a cone is 1/3 the volume of a cylinder that has an equal radius and height.
The volume of a cylinder is equal to πr^2 x height
The volume of a cone equals 1/3 πr^2 x height

Therefore, it should take three cones of water to fill up an equal sized cylinder.
