Question

An aluminum thin-walled sphere is used as a marker
buoy. The sphere has a radius of 60 cm, and a wall
thickness of 12 mm. The density of aluminum is 2690
kg/m3. The buoy is placed in the ocean where the
density of the water is 1030 kg/m3. Determine the
height h between the top of the buoy and the surface
of the water as the radius changes.
