• Identify the perpendicular heights and slant heights of right pyramids and right cones
• Apply Pythagoras’ theorem to find the slant heights, base lengths and perpendicular heights of right pyramids and right cones
• Solve problems involving the surface areas of right pyramids and compare methods of solution
• Apply the formula to find the curved surface area of right cones: $A=\pi rl$, where $r$ is the length of the radius and $l$ is the slant height
• Apply the formula to find the surface area of spheres: $A=4\pi r^2$, where $r$ is the length of the radius
• Solve problems involving the surface area of solids in a variety of contexts including composite solids
