Lesson: Surface Areas of Cones Mathematics • Second Year of Secondary School

In this lesson, we will learn how to calculate the lateral and total surface areas of cones using their formulas.

Lesson Plan

Students will be able to

understand that the total surface area of a cone is the sum of its lateral surface area and the area of its base,
calculate the lateral surface area of a cone,
calculate the total surface area of a cone,
calculate a missing length of a cone when given its lateral surface area or total surface area.
