    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
