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
