1. The problem statement, all variables and given/known data Find the volume of the largest right circular cone that can be inscribed in a sphere of radius 3. 2. Relevant equations V=π*r^2*h/3 A=πr^2 + πrl 3. The attempt at a solution I did multiple things that I'm not sure are correct. I took the derivative for the volume with the value of h set to (9-x^2)^(1/2). The derivative I got was; 3π/2 * (9-x^2)^(-1/2) * (-2x) Not really sure what to do. Think I need a hint on the steps that need to be taken. Picture of problem attached.
