Homework Help: Calculus

Posted by Dewayne on Saturday, March 23, 2013 at 10:12pm.

an open topped cylinder has a volume of 125 cubic inches. determine the radius of the pot that will minimize it's surface area.

What I have so far...

radius =r

keight =h

V=πrh

125/πr=h

SA = πr + 2πr(h)

= πr + 2πr(125/πr)


SA =πr +250/r
