Question

    The diameter of the base of a right circular cone is 4.2

    cm and its height is 10 cm. calculate the volume of the cone.
    A 44.4 cm³ Correct Answer Incorrect Answer
    B 46.2 cm³ Correct Answer Incorrect Answer
    C 48.8 cm³ Correct Answer Incorrect Answer
    D 42.5 cm³ Correct Answer Incorrect Answer

    Solution


    Radius of the cone = Diameter/2

    Radius of the cone = (4.2/2) = 2.1 cm

    Formula for Volume of the cone = (1/3) X π X radius2 X height

    Volume of the cone = (1/3) X (22/7) X 2.1 X 2.1 X 10

    Volume of the cone = 46.2 cm³
