Question

Three pizzerias claim they offer the pizza with the largest circumference.

Each of the 8 slices of Mario's Pizzeria's large pizza has an area of 14.13 square inches.

Each of the 16 slices of Tito's Pizzeria's large pizza has an area of 12.56 square inches.

Each of the 10 slices of Peter's Pizzeria's large pizza has an area of 15.386 square inches.

Place the pizzas in order of least to greatest circumference. Assume all pizzas are circles and assume all pizzas have the same thickness. Use 3.14 for .

Answer 1

For each pizza you can multiply (# of slices)(area per slice) to get the total area of each pizza. Since all circles are similar, largest area also implies largest circumference. That being said, you can confirm this by calculating the radius with A = pi*r^2 and then circumference with C = 2pi*r to confirm/prove.
