if Cost(r)=0.01(2[tex]\pi[/tex]r(adsbygoogle = window.adsbygoogle || []).push({}); ^{2}+v/[tex]\pi[/tex]r^{2}(2[tex]\pi[/tex]r))+0.015(4[tex]\pi[/tex]r+v/[tex]\pi[/tex]r^{2})

v=hpir^{2}

how does one show for the optimal radius/height for any volume i.e. where the cost will be the minimum for that volume?

all my attempts have ended with 0=0

help please? i'll give you cookehz ^^
