Problem with picture attached

I need help on 24. **24 is a continuation of 23 so use the same dimension except for the distance...

Or you can go here http://college.cengage.com/mathemat...alc8e_solution_main.html?CH=00&SECT=a&TYPE=se

Chapter 7, Lesson 5

2. Relevant equations

Volume=∏r^2*Δy

Water= 9800 N/m^3

∫(Volume)(water)(distance)=Work done ??

3. The attempt at a solution

Volume= 4∏Δy

Weight=9800*4∏Δy

Distance is where I'm not too sure about. Would I use (10-y)??

If so then I got...

∫9800*4∏Δy*(10-y), from 0 to 4 = 1,254,400∏ N-m

My answer looks really huge... Did I mess up anywhere?
