Students learn to calculate a cone's curved surface area and total surface area.
As learning progresses, they calculate the area of complex composite shapes involving cones.
Differentiated Learning Objectives
- All students should be able to calculate the curved surface area of a cone using the formula.
- Most students should be able to calculate the total surface area of a cone using Pythagoras' Theorem to calculate the slant.
- Some students should be able to manipulate the formula for the area of a cone to calculate the radius, slant or perpendicular height.
