I was trying to figure out how to solve for the maximum volume of an ice cream cone. Basically waffle cones are made by wrapping
a 5.293 cm radius circle (pancake). I found this by measuring the measurements of the cone shaped like a triangle. And solving for c/sin(c) = 2(radius). However, i dont know what to do next. I know the cone takes the shape of triangle inside of a circle circumscribed around it. So i tried to follow the guide on http://mathcentral.uregina.ca/QQ/database/QQ.09.07/h/astrogirl1.html. But they used a cone inside of a sphere. instead of a circle being wrapped around into a cone. Can someone please help me with this? https://undergroundmathematics.org/circles/cones/appendix to see how cone takes a shape of a triangle in a circle when unwrapped;
