Cannot figure out this calculus problem at all!
Okay...
A cylinder is given, laying on its side. It is 6 feet long, and has a 3 feet diameter. There is a pipe coming into the cylinder one foot above the top of it and extending to the bottom to pump out water. Given F = 9.8 * 1000, what is the work required to pump all of the water out?
Remember, its laying on its side... so the height is the diameter.
What I tried was the following:
Integral from 0 to 1.5: (2)(9800)(4-x)^2(pi)(6)dx
Which comes out to 9800(126pi)
This is incorrect. I have the answer which is supposed to come out to 9800(33.75pi)
Thanks for any help =)
