## Round or square?

If the price is the same, would you prefer to have a 10-inch round pizza or a 9-inch square pizza?

Answer:
The 9-inch square pizza is a better buy.

The area of 9-inch pizza is 9x9 = 81 square inches

and the area of a 10-inch round pizza is πR² = 3.1416 x (10/2)² = 78.54 square inches.
