Given a volume of 1700 cm^3, minimize the surface area of a cylinder.

S=

V=

so, for substitutions:

, which I can put into the S equation to get:

And I think I can simplify the above equation to:

and so is the derivative of this equal to:

I wasn't completely sure if the above equation was right. But continuing on, I would set the derivative equal to 0 and solve for r.

Any help would be greatly appreciated!-I know this is a long post, sorry.
