Question

Cylinder with a mass of 12g has a radius measuring 2cm and height of 6cm what is its density

Answer 1

Answer:

Given:

m = 12 g, the mass of the cylinder

r = 2 cm, the radius of the cylinder

h = 6 cm, the height of the cylinder.

Calculate the volume, V, of the cylinder.

V = πr²h

  =  π*(2 cm)²*(6 cm)

  = 75.398 cm³

By definition,

density = mass/volume.

Therefore,

density = m/V

            = (12 g)/(75.398 cm³)

            = 0.159 g/cm³

            = 0.16 g/cm³ (nearest hundredth)

Answer: 0.16 g/cm³
