Mensuration: Surface Area of a Cone

Overview

There are 3 parts to the course:

(I)   Create your own cone

       Step 1: Materials

       Step 2: Cutting

       Step 3: Form the cone

(II)  Derive the formula of the surface area of cone

       Step 1: Return the cone to its net

       Step 2: Deriving

       Step 3: Total Surface Area of a Cone

(III) Practice questions to check your understanding

At the end of the course, you should have learned to:

• Draw the net of a cone
• Form a cone using given net
• Form an equation to show the relationship between a cone and a circle
• Derive the formula for total surface area of a cone
• Apply the formula to solve questions
