I am trying to find the radius and height of a container with a capacity of 50 in ^3.
I know that the total voume of the cylinder must be 50 in^3, so volume = 50, or pie times radius ^2 = 50 and height = 50/pie times radius ^2.
I need to substitute the expression for height into the for area. I have to find the minimum of area (radius) =
. . .(2 times pie times radius [50/(pie times radius times ^2] )
. . . . . . .+
. . .2 times pie times radius ^2. . .=. . .???
