A cylinder with a mass of 12 g has a radius measuring 2 cm and a height of 6 cm. What is its density? 0.05 g/cm3 0.16 g/cm3 1 g/cm3 144 g/cm3

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
