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.

How to find the volume of a cone and a pyramid

Example problems involving finding volume.
The formula for volume for both a cone and a pyramid equals 1/3Base times height

Example 1 = Find the volume of a cone with a slant height of 13 and a radius of 5 units.

Example 2= Find the volume of a pyramid with a square base with sides of 10 units and a slant height of 13 units.

Volume of a Cone and a Cylinder

Today's video reviews how to find the volume of a cone and a cylinder.
The cone video tackles finding the volume given the slant height and not the cone height. You can use the slant height with the Pythagorean Theorem to find the height,which you can plug into the slant height formula.

The cylinder video gives step by step directions for finding the volume of a cylinder.
