 A cone with an oval as a base 2011-08-03 From Emily:Hi, I was wondering how to calculate the surface area of a cone with an oval as a base (which I think is referred to as an elliptic cone or something like that). I have the both the maximum and minimum radius as well as the height, but I don't have a slant height and I'm not sure how to calculate it and then calculate surface area. I would really appreciate some help. Thanks!Answered by Robert Dawson. An elliptic cone 2004-02-24 From Ben: I am building a model for my architecture class. I need to build a elliptic cone out of chipboard and i have no idea how to do this. The cone needs to be 20in tall and the ellipse has a max radius of 10in and a min radius of 8in. So my question is how do i lay this out on a piece of paper so that i can form the cone after i cut it out. Answered by Penny Nom.
