A tank, shaped like a cone has height 4 meter and base radius 5 meter. It is placed so that the circular part is upward. It is full of water, and we have to pump it all out by a pipe that is always leveled at the surface of the water. Assume that a cubic meter of water weighs 10000N, i.e. the density of water is a 10000- How much work does it require to pump all water out of the tank? Enter the exact value of your answer. N m³ W Joules

A tank, shaped like a cone, has a height of 4 meters and a base radius of 5 meters. It is positioned so that the circular opening faces upward. The tank is filled with water, which needs to be pumped out through a pipe that is kept at the water's surface.

Assume the weight of a cubic meter of water is 10,000 Newtons, implying the density of water is \( 10,000 \, \frac{N}{m^3} \).

Calculate the work required to pump all the water out of the tank. Provide the exact value of your answer.

\[ W = \boxed{} \] Joules

**Diagram Explanation:**

The diagram shows a conical tank filled with water. The cone has a height labeled as 4 meters, and the widest circular opening has a radius of 5 meters, with the water filling the entire cone.
