Question

A slice of pizza has an area of 13.5 sq inches. If the pizza has a radius of 9 inches, how many pizza slices make up the whole pie?

Answer 1

First find the area of the whole circle using the formula pi x r^2:

3.14 x 9 x 9 =

254.34

Then, divide 254,34 by 13.5 to get the number of slices:

254.34/13.5 =

18.84

That’s approximately 19 slices.
