Remember those
cone-shaped milkshake glasses. Ah, the good old days! They looked like they
held a lot of milkshake, but they didn't. I think they were a big scam to fool
us into thinking that we were getting a lot for our money.
See the diagram. The cone looks like it has about 1/2 the volume of the cylinder. But actually, it is exactly 1/3 the volume. That is not much.
