    Question

    The radii of bases of a cylinder and a cone are in the

    ratio 3 : 4 and their heights are in the ratio 2 : 3. The ratio between the volume of cylinder to that of cone is
    A 7 : 8 Correct Answer Incorrect Answer
    B 5 : 7 Correct Answer Incorrect Answer
    C 7 : 5 Correct Answer Incorrect Answer
    D 9 : 8 Correct Answer Incorrect Answer
    E None of these Correct Answer Incorrect Answer

    Solution

    We are given: Radii ratio (cylinder : cone) = 3:4 → Let cylinder's radius = 3r, cone's radius = 4r. Heights ratio (cylinder : cone) = 2:3 → Let cylinder's height = 2h, cone's height = 3h. Find Volumes Cylinder's volume
