A hemispherical water reservoir has radius of 4 m and at the time t = 0 is 6 full of water. At that moment a circular hole with diameter 1 cm develops at the bottom of the tank. How long will it take for all the water to drain from the tank? [Hint: Assume the flat side is at the top and the gravitational acceleration g = 10 m/s^2 .]
