Quizplus · Accepted Answer

Area of a 16-inch pizza = π(8)^2 = 64π
Price per square inch = $15 ÷ 64π ≈ $0.074 per square inch

Area of two 8-inch pizzas = 2(π(4)^2) = 32π
Price per square inch = $14 ÷ 32π ≈ $0.138 per square inch

Therefore, the 16-inch pizza has a lower price per square inch, making it the better buy.
