How do you make a template for a cone three feet in diameter down to two feet in diameter? It has to be about 3' long.

Depends on what you need it for. Personally, I'd probably get a 10' by  3' sheet of whatever, roll it into the appropriate cone shape by experimentation, fasten it in place and cut off the excess. But as others have said, more elegant solutions exist by applying a bit of geometry or just hunting down the formula.

That there stuff takes math and math makes my head hurt.  I think lemonie has the right idea.
