The figure shows an iron ball suspended by
thread of negligible mass from an upright
cylinder that floats partially submerged in
water. The cylinder has a height of 6.70 cm, a
face area of 11.0 cm² on the top and bottom,
and a density of 0.304 g/cm³, and 2.10 cm of
its height is above the water surface. The
water has a density of 1000 kg/m³, and the
iron has a density of 7900 kg/m³. What is the
radius r of the iron ball?
