At a certain pizza parlor, the diameter of a large pizza is 40% larger than the diameter of a small pizza. What is the percent increase in total amount of pizza, from a small to a large?  Pick.
A) 20%	B) 40%	C) 64%	D) 80%	E) 96%
A real world problem —- yum! —- but again, the specifics of the shape don’t matter. Diameter increases 40%, so k = 1.4 in this case. “Amount of pizza” just means the area of the circle, so k^2 = (1.4)^2 = 1.96, which is the multiplier for a 96% increase. That’s the percent increase in area. Answer = 96%
