    The cone will hold a volume of liquid equal to 165.5 cm^3

    Step-by-step explanation:

    In this question, we are told to calculate the amount of liquid that a filter paper cone will hold when it is full.

    This is obviously a volume question and the best thing to do is to calculate the volume of the filter paper.

    Mathematically, the volume of the filter paper can be calculated using the formula;

    V = 1/3 * pi * r^2 * h

    where r is the radius which is Diameter divided by 2 = 9.5cm/2 = 4.75cm

    and height is 7cm

    Using the value of 22/7 for pi and plugging all other values above, we have;

    V = 1/3 * 22/7 * 4.75 * 4.75 * 7 = 165.458333333333 cm^3

    To 1 decimal place = 165.5 cm^3
