Finding the volume of a mug?

I was learning about volume in math today, and I was wondering which one of my coffee mugs held more coffee. My first mug had a diameter of 3.5inches, and a height of 4inches. The formula is pi x radius, squared x height. I’m not concerned about this one, but my other mug has 2 [...]

A cylindrical can has prescribed surface area S. What dimensions for the can yield the maximum volume?

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 a max.V
From (1) & (4), [...]
