Understanding the Volume of a Cone and Cylinder

The video tutorial demonstrates that the volume of a cone is one-third that of a cylinder with the same base and height. The instructor explains the mathematical formula for the volume of both shapes and calculates the volumes using given measurements. A practical demonstration is conducted by filling a cone and a cylinder with water to visually prove the mathematical concept. The video concludes by summarizing the findings and encouraging viewers to subscribe for more math content.

What is the relationship between the volume of a cone and a cylinder with the same base and height?

• The volume of a cone is twice the volume of a cylinder.

• The volume of a cone is one-third the volume of a cylinder.

• The volume of a cone is half the volume of a cylinder.

• The volume of a cone is equal to the volume of a cylinder.
