1. The problem statement, all variables and given/known data A spherical tank is full of water. If radius r = 3m and height h = 1.5m, find the work W required to pump the water out of the spout. (Use 9.8 for g and 3.14 [tex]\pi[/tex]) 2. Relevant equations Work is the integral from a to b of f(x)dx. 3. The attempt at a solution Volume= area * thickness, so I got V= pi*r2dx for any given slice of that sphere. I could be wrong, but I think the density of water is 1000kg/m3, so I multiplied that by the volume to get mass of the water, and then multiplied the mass by 9.8 to get the weight of water. Then I set up my integral from 0 to 1.5 of the answer I got from multiplying all those numbers out * xdx. But I got the wrong answer. So how do I work a problem such as this?
