Cutting A Cylinder

Geometry Level 4

Suppose you have a toilet roll tube. (Just the little cardboard part that's left over once you run out of toilet paper) And, just for fun, you decide to flatten it out and cut a straight diagonal line across it. So, while it's flat it looks like this:

Then you push it back out into a shape of a circular cylinder.

When you are done, if you stand it up vertically and look sideways at it with the tallest part on the right and the shortest part on the left, qualitatively which of the following will it look most like?

And, be honest, how many of you tried cutting one up to answer this question? ;^)
