whys ur handwriting so neat..
its hard to read that scan tho
lets just go over the steps
tell me what you wrote for your surface area equation and volume equation
either way u do same functioon lol
is this what u did?
u 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
ill post a better picture cause i have the whole question finished
just that last step is missing
I 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...
yes looks right
i checked ur first few steps its right upto there
mhm but then i have to find h
i'm not gettingg the right value for h
