    [SOLVED] Pumping water out of cylindrical cone.

    An open tank has the shape of a right circular cone. The tank is 8 feet across the top and 6 feet high. How much work is done emptying the tank by pumping the water over the top edge?

    d=(6-y)

    Weight of water : 62.4

    I've always had a problem solving cylindrical cone problems.

    Any ideas out there? Heh.

    Thanks in advance!

    Nevermind! I figured it out. What I couldn't understand was how the radius changed and how to describe it. (2y/3)
