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+ 2(1200/r)
S`(A)=4∏r-1200/r^2
and i don't know where to go from here, assuming i did this correctly
