    Answer:

    V = 133 cm³

    Step-by-step explanation:

    The formula for the volume of a cone is V = (πr²h) / 3, which is just the formula for the volume of a cylinder but divided by 3, by the way.

    If the diameter is 6, divide that by 2 to get a radius of 3 cm. The height and pi are already given.

    V = ((3.14)(3)²(12)) / 3

    V = (339.12) / 3

    V = 113.04 cm³, or if rounded, it should just be 133 cm³
