    made 6 times made 18 times made 12 times unchanged Advertisement Remove all ads

    SOLUTION

    made 18 timesExplanation;

    Hint:

    Radius of a cone = r

    Height of a cone = h

    Volume of the cone =

    13 πr2h cu.units

    When the radius is increased three-time (tripled) and the height is doubled

    Radius is 3r and the height is 2h

    Volume of the new cone

    = h 13π(3π)2×2h = h 13π×9π2×2h = rh 13πr2h (18)

    Volume is increased 18 times.
