Students learn how to calculate the volume of a cone using the base area and perpendicular height.

As learning progresses they are taught to use Pythagoras' Theorem to find the perpendicular height when the slanted length is given.

**Differentiated Learning Objectives**

- All students should be able to calculate the volume of a cone when given its perpendicular height using the formula.
- Most students should be able to calculate the volume of a cone using Pythagorasâ€™ Theorem to calculate the perpendicular height.
- Some students should be able to calculate the volume of a frustum as the difference in volume between two cones
