a solid iron pole consists of a cylinder of height 220 cm and base diameter 24 cm which is surmounted by another cylinder of height 60 cm and radius 8 cm find the mass of the pole given that 1 cm cube of iron has approximately 8 gram mass (pie = 3.14)

From the figure, it can be observed that
Height (h1) of larger cylinder = 220 cm
Radius (r1) of larger cylinder = 12 cm
Height (h2) of smaller cylinder = 60 cm
Radius (r2) of smaller cylinder = 8 cm
Mass of 1iron = 8 g
Mass of 111532.8iron = 111532.8 × 8 = 892262.4 g = 892.262 kg
Height (h1) of larger cylinder = 220 cm
Radius (r1) of larger cylinder = 12 cm
Height (h2) of smaller cylinder = 60 cm
Radius (r2) of smaller cylinder = 8 cm
Mass of 1iron = 8 g
Mass of 111532.8iron = 111532.8 × 8 = 892262.4 g = 892.262 kg
