1. The problem statement, all variables and given/known data I'm wondering whether or not it is possible to get the area of the base of an elliptical, non-right cone if the following two parameters are known: - length from center of ellipse up to vertex - angle that the sides make Here is a simple visual: http://i.imgur.com/M6jT5.png 2. Relevant equations [tex]A=\pi ab[/tex] 3. The attempt at a solution I've tried looking at geometry guides with no success. I'm thinking I might be able to use some clever trig and drop a right angle down from the vertex in order to get the length of the semi-minor/major axis, but I can't reason it out. any advice would be appreciated.
