The tap in the garden was closed in appropriately resulting in the water flowing
freely out of it which forms a downward narrowing beam. The beam of water
has a circular cross-section, the diameter of the circle is 6 mm at one point and
3 cm below it is only 3 mm as shown in figure. If the rate of water wasted is
(x**) mL/minute then find the value of x. (Neglect the effect of viscosity and
surface tension of the flowing wate.r.)​
