THE LESSON:

Today's lesson is where we put all our learning of Circles, Sectors, Perimeters and Areas together.

For the purpose of geometry, Composite means:

"A complex shape, made up of (composed of) two or more other shapes".

Many shapes in life are not perfect circles or squares. A cricket ground or football oval may not always be rectangular, or oval shape.

Definition: Composite Shape

Your humble 'tin can'.
Circles top and bottom, joined by a cylinder.

Question:

How would you work out it's surface area?

(Remember - there is a top, bottom
and side).
