6. (10 points) When a hydrometer (see the figure below) having a stem diameter of 0.30 in. is placed in water, the stem protrudes 3.15 in. above the water surface. If the water is replaced with a liquid having a specific gravity of 1.10, how much of the stem (in units of in.) would protrude above the liquid surface? The hydrometer weighs 0.042 lb.
