Lesson Plan: Volumes of Cones | Nagwa Lesson Plan: Volumes of Cones | Nagwa

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.


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.


Students should already be familiar with

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


Students will not cover

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