sorry about that mark, just that I am very confused at this

alright thanks sharks and lckurtz, ill try my best

sharks is it possible if you show me your steps?

oh okay, thank you

So the correct formula would be 1200pi=2*pi*r^2+pi*r*h but because it is an open top it would be 1200pi=pi*r^2+pi*r*h and were trying to maximize the volume, v=pi*r^2*h h=1200pi/(pi*r^2+pi*r) v=pi*r^2*((1200pi/(pi*r^2+pi*r)) am i on the right track now?

i thought the total material would be 1200, so how would i go about this problem?

If 1200∏ cm^2 of material is available to make a cylindrical can with a circular base an open top, find the largest possible volume of the can. the formulas i used: v=∏* r^2 * h surface area = 2∏r^2 + 2rh my attempt: 1200=r^2h∏ h=1200/r^2∏ SA=2∏r^2+2∏r(1200/∏r^2) =2∏r^2+...
