Find the weight of a solid cylinder of radius 10.5 cm and height 60 cm if the material of the cylinder weigh 5 g per cm3.
Given,
Radius of cylinder = 10.5 cm
Height of cylinder = 60 cm
∴ Volume of cylinder = πr2h = 
× 10.5 × 10.5 × 60 = 20790 cm3
∴ Weight of cylinder = volume of cylinder × wt. of cylinder per gram
= 20790 × 5 g = 103950 g = 103.95 kg
