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 5.80 cm, a face area of 11.0 cm² on the top and bottom, and a density of 0.282 g/cm³, and 1.80 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?

Question
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 5.80 cm, a face area of 11.0 cm² on the top
and bottom, and a density of 0.282 g/cm³, and 1.80
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?
