Question

A 6 inch personal pizza has 610 calories, with 240 of those from fat. A 16 inch pizza is cut into 8 slices. Estimate the number of calories in one slice of a 16 inch pizza.

Answer 1

The ratio of the area is as the square of the linear ratio.

In this case (16)² / (6)² or 7.1111

The larger pizza has (7.1111)(610) calores.

Divide that number by 8.
