Totally agree, and sitting in a Starbucks I was able to sketch that out, as per the reply to AndrewKirk. Thanks much!

Thank you AndrewKirk, that was very intuitive and helpful. My first new attempt used the similarity between a representative 'proportional nested cone' and the overall cone, getting that H/R = h/r. I then integrated from 0 to r, the lateral surface area of the representative cone which is then...

Homework Statement Wikipedia tells me that I can obtain the surface area of a sphere by realizing that the volume of a sphere is equivalent to the infinite sum of the surface areas of hollow, nested spheres, sort of like little Russian dolls. That makes sense, and then differentiating both...
