The radius of a right circular cyliner increases at a constant rate. Its altitude is a linear function of radius and increases three times as fast as radius. When the radius is 1 cm the altitude is 6 cm radius is 6cm, the volume is increasing at the rate of 1 Cu.cm/sec. When the radius is 36 cm Volume is increasing at a rate of n cu. cm/sec. The value of 'n' is divisible by
