here is your answer
volume of cylinder =πr^2h
=22/7*10.5*10.5*60
=20790cm^3
=20790*5
=103950gm

Given :
Radius of the solid cylindrical Marek = 10.5 cm
Height of the cylinder = 60 cm
To Find :
It's weight if it's density = 5g/cm³
Solution :
We know that we can find its mass if we know the volume of the metal.
Finding volume of the cylinder =
πr²h
= 22/7 × (10.5)² × 60
= 20790 cm³
Then mass = Volume × Density
= 20790 × 5 = 103,950 g = 103.95 kg
The required mass = 103.95 kg
