Well, I’m not sure we even need
to work this one out. Two times
twelve is more than eighteen, so
MegaSlice’s deal is more pizza.
Frank: Not so fast. I’m not sure it’s that simple.
Joe: What’s hard about it? 12 + 12 = 24. 24 is way more
than 18. Game over.
Jim: But that’s not area—that’s diameter!
Jim: Well, I’m not sure that you can just add up diameters
and then compare them instead of comparing area.
Joe: Why not? Anyway, we don’t even know how to find
the area of a circle. Hey—is this making you guys hungry?
Frank: Shut up! This is serious. We need to find a way to
compare the actual pizza area, and not just the diameters.
Jim: Agreed, but where do we start?
Frank: Well, I guess we should just start from what we do
know and go from there.
