1. Gravel is falling onto a conical pile at the rate of 10 m3
/min. The coarseness of the gravel is such that the pile is always
in the shape of a cone with its height equal to two thirds of its
radius. How fast is the height of the pile increasing when the pile
is 5 meters high? [Recall that V = 1 3 πr2 h.]
