Question

At a local pizza parlor, the large pies have a diameter of 16 inches. each large pie can be cut into either 8 slices or 12 slices based on customers preference. how much larger is the area of a slice of pizza from the 8 piece pie then the area of a slice of pizza from the 12 piece pie round your answer to the nearest tenth of a square inch (please explain how you got the answer)

Answer 1

Area=Pi r^2

A=3.1414592 x 8^2

A=201.06 Inches^2

201.06/8 =25.13 inch^2-the size of each of the 8 slices

201.06/12=16.76 inch^2-the size of each of the 12 slices

25.13/16.76=1.50 - 1 =.50 x 100 =50% bigger-the 8/12 slices.

You could just as well divide the diameter of the pie by 8 and 12 and the difference would be the same, or 50% larger.
