A a conical container of radius 5ft and height 20ft is filled to a height of 18ft of a liquid weighing 50.6lb/ft^3. How much work will it take to pump the contents to the rim? How much work will it take to pump the liquid of a level of 2ft above the rim?
So I got integral (50.6pi/1)y^2(18-y)from 0 to 18 to get 125546, but that wasn't the right answer. Please help! What's the number before y^2 supposed to be?
BTW the right answer was 125452
