When sizes of pizzas are quoted in inches, the number quoted is the diameter of the pizza. A restaurant advertises an 8-{\rm inch} "personal pizza." If this 8in pizza is the right size for one person, how many people can be fed by a large 16 in pizza?

You can do this as a ratio of the areas, where the area of the personal pizza is 16*pi in^2 and the area of the large pizza is 64*pi in^2.  (64*pi)/(16*pi)=4
