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)
You can calculate the area of the whole pizza according to the formula: S=1/2*π*r². And the area of 8 piece is 1/8S while the area of 12 piece is 1/12S. The answer should be 1/8S-1/12S=4/3π.
