1. The problem statement, all variables and given/known data
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/mathemati...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 (10y)?? If so then I got... ∫9800*4∏Δy*(10y), from 0 to 4 = 1,254,400∏ Nm My answer looks really huge... Did I mess up anywhere?
