Surface Area

L.O – To be able to calculate the surface area of a sphere, cone and cylinder. Also, to the able to match 3D shapes with their associated nets

Surface area = total area of all the outer surfaces of a 3D shape added together

Sphere :

Make sure you check which formulas are on the formula sheet of your exam!

The ones which aren’t, you will have to learn.

Example 1:

Calculate the surface area of this sphere

– Surface area = 4πr2

= 4 x π x 32

= 36π

Example 2:

Calculate the surface area of a cone with r = 5cm and l = 11cm

– Surface area = πrl + πr2

= (π x 5 x 11) + (π x 52)

= 55π + 25π

= 80π

Example 3:

Calculate the surface area of this cylinder

– Surface area = 2πrh + 2πr2

= (2 x π x 2 x 5.6) + (2 x π x 22)

=

Questions:

Net:

A net is a 2D representation of a 3D shape.
