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 5.90 cm, a face area of 12.0 cm² on the top and bottom, and a density of 0.262 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? Number i 1.01 Units m
