# A solid iron pole consists of a cylinder of height 220 cm and base diameter 24 cm

Mensuration (C10)
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^{3} of iron has approximately 8 gm mass. (Use π = 3.14)

### Answer

Total volume = 3.14 (12)^{2} (220) + 3.14 (8)^{2} (60)

= 99475.2 + 12057.6

= 111532.8 cm^{3}

Mass = (111532.8 × 8)/1000

= 892.262 kg
