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.

The area of 1 slice of pizza is 56.5 cm² .

Step-by-step 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)

there are 70 more legs than eyes at the dog show (196 – 126 = 70). dogs have two more legs than eyes, and humans have the same number of legs as eyes. thus 70 is twice the number of dogs at the show, so the number of dogs is half of 70, which is 35. to get the number of humans, subtract 35 from 63: 63 – 35 = 28.
