A tank, shaped like a cone has height 9 meters and base radius 1 meter long. 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 - 10000- How much work does it N m³ require to pump all water out of the tank? Enter the exact value of your answer. W = Joules
