    V = '1/3 * πr² * h

    The half of a diameter is the radius. So, r = d/2. Substituting the values

    V = 1/3 * (3.14) (5/2) ² * 7

    V = 45.79 or 46 cm³

    The answer is letter B.

    The formula of finding volume of a cone is 3.14 r squared x h/3

    so our volume is 3.14 x 2.5 x 2.5x 7/3 = 46 cu. cm
