Question from lisa, a parent:

We need to make a cone that has the following dimensions.
14-3/8" diameter on large end
13-3/8" diameter on small end
4" tall

What are the dimensions I need to cut in order to make a cone with one seam?

Hi Lisa.

Take a look at the detailed examples we wrote up

here: http://mathcentral.uregina.ca/QQ/database/QQ.09.06/s/mike1.html

and here: http://mathcentral.uregina.ca/QQ/database/QQ.09.07/s/janet1.html

The numbers are different, but the technique is identical to your question.

Cheers,
Stephen La Rocque
