hye tiny-tim! s = \sqrt{r^{} + h^{}} i don't know how to put the "surd". sorry ok. :) in the above equation, i do mean, s = surd(r^2 + h^2).

ooppss tiny-tim, i am forgotten to tell you what is r, h, and s actually. actually, s = side of the conical container (shown in picture). r = radius of conical container (shown in picture). h = height of the conical container (shown in picture)

hye tiny-tim! thanks for your concern on this question.. for your information, i am attaching the picture of the conical container..may help you to solve this question..thanks in advance! ;)

Design the optimal conical container that has a cover and has walls of negligible thickness. The container is to hold 0.5 m^3. Design it so that the areas of its base and sides are minimized. information : 1) areas of the sides = (pi) x r x s 2) areas of the base = (pi) x (r^2) 3)volume of...
