Pizza Casbah is known for their large pizzas. The diameter of the pizza is 18 inches. Pizza Casbah recently began a MEGA-PIZZA challenge where two people must complete a 30-inch pizza to get their name on the wall of fame. Greg can eat an entire large (18-inch) pizza by himself and believes that if his partner can eat the same amount, they should be able to eat a 36-inch pizza. Explain why you agree or disagree. Greg knows the maximum he can eat is the amount of pizza in an 18-inch pizza. How many square inches of pizza will his partner need to eat in order for them to win the challenge?
