That's what I tried, but when you substitute for h and differentiate the result is in V, r and k. When the expression is minimized it is in terms of V,r,k,and h. I just don't know how all the h got back into the equation along with V. If i set the derivative equal to 0 and solve for V, then...

My class is doing an optimization problem, The shape of a can. I have attached a copy of the problem. I have done problems 1 and 2 and now am stuck on problem 3. What I've tried so far is to differentiate the function 4sqrt3 r^2 +2Pi rh +k(4Pir +h) with respect to r where h=v/Pir^2. I know...
