Best ResponseYou've already chosen the best response.0Volume of cylinder = (Area of the Base)*(Height) The base of a cylinder is a circle so, Area of a circle = (pi)r^2 The initial Height is X, after the metal is dropped it turns to x+3.4

Best ResponseYou've already chosen the best response.0\[V' = \pi (3^{3})h = 9{\pi}h\]\[V'' = \pi(3^{3})(h+3) = 9h{\pi}+27{\pi}\] \[V''  V' = Vmetal\]\[9h{\pi}+27{\pi}  9{\pi}h = 27{\pi}\]

Best ResponseYou've already chosen the best response.0oh okay, but on the first equation for the after metal volume shouldnt it be (h+3.4)? or no..
