    Cone volume = (pi*r*r*h) / 3

    where r is radius and h is height

    Put in what we know

    pi is about 3.1415

    4 = (3.1415*3*3*h) / 3

    4 = 28.274*h/3

    4 = 28.274/3*h

    4 = 9.425*h

    h = 4/9.425=0.424

    and that would be in inches so

    Height is about 0.424 inches.

    It can be rounded to 0.42
