    Answer:

    The volume of the coin is 4.236 x 10⁻⁷ m³

    Explanation:

    Given;

    radius of a coin, r = 1.06 cm = 0.0106 m

    thickness of the coin, h = 1.2 mm = 0.0012 m

    The volume of the coin is given by;

    volume = Area x thickness

    Area of the coin = πr² = π (0.0106)² = 3.5304 x 10⁻⁴ m²

    The volume of the coin = (3.5304 x 10⁻⁴ m²) x (0.0012 m)

    The volume of the coin = 4.236 x 10⁻⁷ m³

    Therefore, the volume of the coin is 4.236 x 10⁻⁷ m³
