Question

A 6 inch perosnal pizza has 570 calories with 240 o fthe from fat. a 16 inch pizza is cut into 8 slices. Estimate the number of calories in 1 slice of pizza?

Answer 1

Answer:  

The number of calories is going to be pretty close to proportional to the area of the pizza.  Figure out the area of a 6-ince pizza, and then figure out the area of a 14-inch pizza.  Then you're going to get a proportion:

 

(Area of 14 inch pizza) is to (Area of 6 inch pizza) as (Number of calories in 14 inch pizza) is to (Number of calories in 6 inch pizza.

 

You know the areas of both sizes and the number of calories in the 6 inch pizza, so you should be able to find the number of calories in the 14 inch pizza.

 

Then divide by 8 to get the number of calories in each slice.
