An open tank has the shape of a right circular cone (see figure). The tank is 8 feet across the top and 6 feet high. How much work is done in emptying the tank by pumping the water over the top edge? (The weight-density of water is 62.4 pounds per cubic foot.)

It's late here and I've got early lectures so I can't type up your answer until tomorrow, but here's an example which might help before I can reply:
What you said before isn't right because the width depends on the height. We know Work Done =Density * Area of disc * Height of disc * Distance
We have density and distance. The rest we can find from integrating.
okay, ill see if i can get anywhere & let you know! thank you!
