please show me how to work this problem using tools you learn from Calculus 3
Let r be the radius of the base circle & h the height of
the cylindrical can. Then
2pir^2+2pirh=S=> (pi=3.141592..., the can-cover is counted)
h=[S/(2pir)-r]-----(1)
The volume V of the cylindrical can is given by
V=pir^2h=>
V=pir^2[S/(2pir)-r] (from (1))=>
V=rS/2-pir^3=>
V'=S/2-3pir^2=>--(2)
V"=-6pir-----------(3)
V'=0=>
r=sqrt(S/(6pi))------(4)
from (3),(4),get
V"(S/(6pi))<0=> (4) gives ...
