Surface Area of a Cone

Students learn how to calculate the curved surface area of a cone and total surface area of a cone by considering the net shape of a sector and circle.  As learning progress they calculate the are 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.
