Question

A pizza has 8 slices. The pizza has a radius of 12 cm.

What is the area of one slice of pizza? Give your answer to 1 decimal place.

Answer 1

One slice of pizza will be 56.5486677646 cm long.

Answer 2

The area of 1 slice of pizza is 56.5 cm² .

Explanation:

In order to find the area of one slice, you have to find the area of the whole pizza using the area of circle, A = π×r² where r represents radius :

Let r be 12 cm,

A = π×12²

= 144π cm²

It is given that this pizza can be cut into 8 slices. So you have to divide it by 8 :

144π ÷ 8

= 56.5 cm² (3s.f)
