Question from JUAN:

i need to create a template for a cone that has a 4 " opening at top, a 14" base and 12" tall.Can u tell me how to achieve this?
u have similar problems but when i try to do it , is not coming up right , please help..

Hi Juan,

There are two identical problems but with different numbers in our database. They are Penny's solution to a Russell's problem and Stephen's solution to Mike's problem. With the diagram and notation in Russels problem you have

|CD| = 7 inches, |BE| = 2 inches and |BC| = 12 inches.

Using these two existing solutions work through the calculations with your numbers. If you still have difficulties show us what you did.
