Find the mass of 200 steel spherical ball bearings, each of which has – InterviewSolution

1.	Find the mass of 200 steel spherical ball bearings, each of which has radius 0.7 cm,given that the density of steel is 7.95 g/cm. (Mass Volume x Density)
Answer» Radius = 0.7 cmvolume = 4/3pir³ = (4×22×7×7×7)÷(3×7×10×10×10) = 1.44 cm³density = mass/volume7.95 = mass/ 1.44mass = 11.448gmass of 200 such balls = 2289.6g
