Best ResponseYou've already chosen the best response.1woops I was actually close The real answer is \[1/3 * pi * r^2 * h\]

Best ResponseYou've already chosen the best response.1My first guess (which was wrong) came from my udnerstanding that a the area of a right triangle is the 1/2 base * height. I then know that the base is circular so the base will be pi*r^2 Note that ANY volume will require an area times a height.

Best ResponseYou've already chosen the best response.0What I try is.. as it was found that \[r = \sqrt{c ^{2}h ^{2}}\] so the cross sectional area is A(h)= pi r^2 = pi (c^2h^2) from the drawing.. a=0, b=h so the volume is \[\int\limits_{0}^{h} A(h) dh = \int\limits_{0}^{h} pi(c^{2}h^{2}) dh\]
