Mathematics Unit 29: Pizzas

Presentation transcript:

Problem 7.1 The Pizzeria sells small, medium, and large pizzas. A small is 9 inches in diameter, a medium is 12 inches in diameter, and a large is 15 inches in diameter. Prices for cheese pizzas are $6.00 for small, $9.00 for medium, and $12 for large.

Part A Draw a 9-inch, a 12-inch, and a 15-inch “pizza” on centimeter grid paper. Let 1 centimeter of the grid paper represent 1 inch on the pizza. Estimate the radius, circumference, and area of each pizza. (You may want to use string to help you find the circumference.)

Part B Which measurements – radius, diameter, circumference, and area – seems most closely related to price? Explain your answer.

Follow-up Use your results to write a report about what you consider the best value of the pizza options at The Pizzeria.
