## Homework Statement

given, diameter and height of pool, depth of water, density of water and gravitational acceleration.

g = 9.8

height is 4m

2r = 20m

depth of water = 3.5m

density =1000kg/m^3

So, I'm supposed to find how much work is needed in joules to lift the water out of the pool.

## Homework Equations

could I use density times gravity times volume to get my force?

is my distance for my water to travel 4.5m?

## The Attempt at a Solution

Anyways, I've tried to use my volume for the pool and the volume I have of water * density *gravity to come up with my force and then used 4.5m as my distance to come up with my work needed to lift water out of a pool. I ended up with 1.08E7 joules but that's incorrect so any help would be appreciated.

BTW, this is a cal 2 problem/integration problem
