1) hemisphere of radius 5 m at the bottom

2) a cylinder of radius 5 m and height 10 m in the middle

3) a circular cone with base radius 5 and height 4 m at the top

The top of the tan is 2 m below the ground surface and is connected to the surface by a spout. Find the work required to empty the tank by pumping all of the water out of the tank up to the surface

Density of water = 1000kg/m^3

Gravity = 10m/s^2

I am doing it so I find the work done of all three (three different parts) then adding the all 3 work done to get the final answer. I really just need help solving the cone I do not even know where to begin! Someone please help me solve this!

- calculus 2 or physics -
**Reiny**, Wednesday, November 17, 2010 at 4:44pmI can help you with finding the volume of the different shapes

volume of hemisphere = (1/2)(4/3)π(5^3) = (50/3)π

volume of cyliner = π(5^2)(10) = 250π

volume of cone = (1/3)π(5^2(4) = (100/3)π

The rest of the question deals with concepts of physics, of which I have little knowledge.
