Need help with the optimization of volume of 3 dimensional shapes.

A right circular cylinder is inscribed in a cone with height H and base radius R. Find the largest volume of such a cylinder (you should assume they are rotated about the same axis).

If you could please solve in a step by step manner and explain each step, I would greatly appreciate it. Thank you.

Have you copied down everything from the question? The largest possible cylinder at the moment is with infinite radius and infinite height...

Re: Need help with the optimization of volume of 3 dimensional shapes.

let the cone be formed by an isosceles triangle with vertex angle on the y-axis and base on the x-axis.

slant of cone in quad I is the line

radius of the cylinder

height of the cylinder

remember H and R are constants, I'll leave you to finish it ...
