A cylindrical shaped object has a density of 2 g/cm3 and a radius of 5 cm. It is placed in a tank of water (density=1 g/cm3). The object displaces water and floats partially submerged. Calculate the volume of the object that is submerged in the water. (Note: use Archimedes' principle to solve the problem).
