    Answer:

    The new volume will be 3 3/8 or maybe 27/8 of its original volume.

    Step-by-step explanation:

    Cone Volume = PI * radius^2 * height / 3

    So if radius = 1 and height = 1 then volume = 1.0472

    When radius = 3 and height = .375 then volume = 3.5343

    Volume increases by 3.5343 / 1.0472 = 3 and 3/8
