At the local pizza parlor, the large pies have a diameter of 16 inches. Each large pie can be cut into either 8 or 12 uniform slices based on customer preference. How much larger is the area of a slice of pizza from the 8 piece pie than the area of a slice of pizza from the 12 slice pizza? Round your answer to the nearest tenth of a square inch.
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.
