[check my work ]
A cylindrical container, with a volume of 4000cm³ is being constructed to build candies. The cost of the base and lid is $0.005/cm², and the cost of the side walls is $0.0025/cm². Determine the dimensions of the cheapest possible container.
Okay so I finished the problem and got the right radius but i'm having problems finding the height !

Best ResponseYou've already chosen the best response.0u can rewrite h as a function of r or r as a function of h and substitute into 2nd equation and take the derivative solve for the critical points, and see what dimensions minimize cost

Best ResponseYou've already chosen the best response.1I don't know what the above discussion is going into, but if you have found out the radius, just substitute the value in pi*r^2*h = 4000 since the volume of cylinder is given by pi*r^2*h...
