When an object that is denser than water is dropped into a vessel of water, the object
sinks to the bottom and displaces water, making the water level rise in the vessel.
The volume of water displaced is equal to the volume of the submerged object. A
60cm diameter steel ball is dropped into a cylindrical vessel of water, sinks to the
bottom and is fully submerged. Before dropping the ball in, the water is 125 cm deep
and after the ball is dropped in, the water level rises 5cm. Find the radius of the
cylindrical vessel.
