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
of iron has approximately 8 g mass. (Use π = 3.14)
Solution:
Radius of big cylinder
cm
Radius of small cylinder
cm
Height of big cylinder
cm
Height of small cylinder
cm
Volume of big cylinder
Volume of small cylinder
Volume of Pole =Volume of Big Cylinder + Volume of small Cylinder = 99475.2+12057.6 = 111532.8
1
of iron =8 g
111532.8
of iron
g = 892.262 kg
