Question

A circular pizza has an area of 900 cm2. If a slice is cut with an angle of 40° at the centre, what is the area of the slice?

Answer 1

The area of the pizza is 90 square centimeters.

The number of degrees in a circle is 360.

360 / 40 = 9

The pizza will deliver 9 slices if each slice creates an angle of 40 degrees at the center of the pizza.

Each slice is the same size, so the area of each slice has to be 90 / 9 = 10 square centimeters

= 10cm2
