The problem: "One can of pumpkin pie mix will make a pie of diameter 8 in. If two cans of pie mix are used to make a larger pie of the same thickness, find the diameter of that pie."
I have absolutely no idea where to start. I assume something to do with pi, as in the symbol. After that I'm lost.

it sounds to me like the amount of pumpkin pie mix is analogous to area.
and A = [pi]r^2
so, if my guess on the area thing is correct, you can find the area of the first pie, double it, plug it back into the area equation, then solve for r and double that to find the diameter of the larger pie.
does that make sense? o 3o;
