Mod note: Moved from technical math section, so is missing the homework template. A right triangle the hypotenuse of which is c revolves about a small side. A right circular cone is formed. Find the largest possible volume of the cone. Vcone: pi*r^2*(h/3) I don't get why they mentioned the hypotenuse, since it is not even in the volume formula... Since it is a 'right' triangle, shouldn't the maximum height of the cone be 1? But I still don't know which extreme value I should search for... (The solution should be: 1/(9*sqrt3) * c^3 * pi ) Could someone please help me to?
