Two cylinders with the same mass density rhoc = 713 kg / m3 are floating in a container of water (with mass density rhow = 1025 kg / m3). cylinder #1 has a length of l1 = 20 cm and radius r1 = 5 cm. cylinder #2 has a length of l2 = 10 cm and radius r2 = 10 cm. if h1 and h2 are the heights that these cylinders stick out above the water, what is the ratio of the height of cylinder #2 above the water to the height of cylinder #1 above the water (h2 / h1)? h2 / h1 =
