Acylinder 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)

0.16 g/cm³
