The main weapon on a military tank is a cannon that fires a blunt projectile specially designed to cause a shock wave when it hits another tank. The projectile fits into a finned casing that improves its accuracy. Calculate the mass of the projectile, assuming it is a cylinder of uranium (density = 19.05 g/cm3) that is 105 mm in diameter and 30 cm in height. The volume of a cylinder is given by the equation V = r2h

2.97 LDPE has a density in the range of 0.915—0.935 g/cm3, and HDPF has a density in the range of 0.940—0.965 g/cm3. You receive a small disk, 2.0 cm high with a 6.0-cm diameter, from a manufacturer of polyethylene, but its label is missing. You measure the mass of the disk and find that it is 53.8 g.
