# Lesson Plan: Volumes of Cones Mathematics • 8th Grade

This lesson plan includes the objectives, prerequisites, and exclusions of the lesson teaching students how to calculate volumes of cones and solve problems including real-life situations.

#### Objectives

Students will be able to

• recall the formula for the volume of a cone,
• find the volume of a cone with known side lengths and radius (slant height or perpendicular height given),
• find the volume of a cone where the area of the base is given and the perpendicular height can be calculated,
• calculate a missing length of a cone when given its volume,
• use knowledge of the volume of a cone to solve problems presented as real-life systems.

#### Prerequisites

Students should already be familiar with

• slant height and perpendicular height of a cone,
• right cones,
• the Pythagorean theorem.

#### Exclusions

Students will not cover

• oblique cones,
• pyramids,
• the surface area of a cone.
