Layout of a truncated cone

ahhhh

Im getting r=23.333333 R=37.333333
inner circle is 19.29 degrees

according to the page: the outside radius R is simply w more than the inside radius r so the answer you got appears to be way off.

ahhhh

Im getting r=23.333333 R=37.333333 Im not sure how accurate this is, but I'll rework it

*EDIT** I guess I quoted you as you edited your post, LOL

Those numbers look right, actually!

Roll a piece of paper into a cone, cut the ends off so they sit flat when it's set down on a table or something. Cut the cone down the length of the "height", so that it unfolds like the diagrams on the length. I think you'll understand it a little better.

The radii of the two diameters created, won't be the radii used if you were making two seperate cylinders that didn't taper.

The two radii will be a number bigger than any measurement given, as the length isn't short compared to the taper. If that makes sense.
