Question

The radius of a solid metal cylinder is 10.5cm and height 60cm. Calculate the mass of the cylinder if the density of metal of cylinder is 5gm/cubic cm.​

Answer 1

here is your answer

volume of cylinder =πr^2h
=22/7*10.5*10.5*60
=20790cm^3

=20790*5

=103950gm

Answer 2

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
