A mexican restaurant sells quesadillas in two sizes: a “large” 12 inch-round quesadilla and a “small” 6 inch-round quesadilla. Which is larger, half of the 12-inch quesadilla or the entire 6 inch quesadilla?

what i would say the best answer is a. 40.5

multiplication is multiplication.   it might feel harder depending on what level of math you are in, but generally it will be the same old stuff, while implementing some new concepts and methods of solving work.
