Sand is poured onto horizontal ground at a rate of 50 cm3 /s. The sand forms a right
circular cone with its base on the ground. The volume of the cone increases in such a way
that the radius of the base is always three times the height of the cone. Find the rate of
change, in cm/s to 3 significant figures, of the radius of the cone when the radius is 10 cm.
