# 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 cm^{3}.

Answer :

Given,

Radius of cylinder = 10.5 cm

Height of cylinder = 60 cm

∴ Volume of cylinder = πr^{2}h = × 10.5 × 10.5 × 60 = 20790 cm^{3}

∴ Weight of cylinder = volume of cylinder × wt. of cylinder per gram

= 20790 × 5 g = 103950 g = 103.95 kg
