    It fills the cylinder up to 10 cm.

    The volume of a cylinder is given by the formula

    V = πr²h, where r is the radius of the base and h is the height of the cylinder.

    The volume of a cone is given by the formula

    V = 1/3πr²h, where r is the radius of the base and h is the height of the cylinder.

    Since the base of the flask and the cylinder are the same, this means r is the same number in both formulas.

    Since the height of the flask and the cylinder are the same, this means h is the same number in both formulas.

    This means that the only difference in the formulas is that the formula for the cone flask is 1/3 the formula for the cylinder.

    The water that fills the cone flask will fill 1/3 of the cylinder; 1/3 (30) = 10
