A hemispherical bowl of radius 8cm contains water which is flowing into it at a constant rate.When the height of the water is h cm, the volume V cm3 of the water in the bowl is given by
V=pie(8h*2- 1/3h*3)
Find the rate at which the water level is rising when h=5, given that the time taken to fill the bowl is 2 mins.
