Density=mass/volume
mass=1 kg
volume=pi * radius^2 * length
100mm=0.1m and 50mm=0.05m
length=0.1m and radius=0.05/2
Plug in the values and solve for the volume of the cylinder, and then solve for density after calculating the volume. Your answer will have units of kg/m^3
Density of H2O=1kg/m^3
Plug in values and solve for the specific gravity
Specific gravity=density of cylinder/density of water
****Note: specific gravity is unitless.
