A solid cylinder has a radius of 0.05m and a height of 0.03m. The cylinder is composed of two different materials with materials with mass densities of 1950 kg/mand 1470 kg/m3. The cylinder contains an equal mass m of each of ther two materials, so that the total mass is M = 2m. What is the mass m? The volume of a cylinder is V = pie rh.
