Volume of rock is 13.5pi cubic inches

Explanation:

When a rock is completely submerged in water, the level of water rises by the increase in the volume of water.

As the radius of cylinder is 3 inches and rise in level of water is 1.5 inches,

increase in volume of water is pixx3^2xx1.5=13.5pi cubic inches.

Hence, volume of rock is 13.5pi cubic inches.
