Floating Cylinders
 ...This image is
NOT to scale! Two cylinders with the
same mass density rC = 713 kg / m3 are floating in a
container of water (with mass density rW = 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 =
