Best ResponseYou've already chosen the best response.0you mean \[(3\pi Vh)^3  s^2h^2 + 9V^2\] so what's the problem?

Best ResponseYou've already chosen the best response.0excuse me, you're the one who asked for help, why are you being so boiled up? It's rude, please be polite.

Best ResponseYou've already chosen the best response.0all you have to do is substitute V and S in the equation and simplify.

Best ResponseYou've already chosen the best response.0and when you do that you get in the end.\[\pi^2r^2h^4  4\pi r^4h^2(r^2 + h^2) + 1/3 \pi r^2h\]

Best ResponseYou've already chosen the best response.0ofcourse you won't get it corret in the first place, try again. What are the options, tell me?

Best ResponseYou've already chosen the best response.0I've made a mistake, in the end of the answer I gave you above it's supposed to be \[3\pi r^2h\] and note 1/3 pir^2h

Best ResponseYou've already chosen the best response.0here the solution is : first you'll substitute the given in the formula and you will end up with this: \[\pi^2 r^2h^4  4 \pi^2r^4h^2(r^2 + h^2) + \pi^2r^4h^2\] then simplify, it's a long step but in the end you will end up with : \[3\pi^2r^2h^4  3\pi^2r^2h^2\] = \[3\pi^2h^2(r^2h^2  r^2h^2)\] = \[3\pi^2h^2\] x 0 = 0 That's it :)
