  • question_answer
    The height of a cylinder is 14 ran and it's curved surface area is \[264\,\,c{{m}^{2}}\] The volume of the cylinder is?

    A) \[308\,\,c{{m}^{3}}\]              

    B) \[1232\,\,c{{m}^{3}}\]

    C) \[364\,\,c{{m}^{3}}\]              

    D) \[396\,\,c{{m}^{3}}\]

    Correct Answer: D

    Solution :

    Let the radius of cylinder be r, then \[r=\frac{264}{2\pi \times 14}=3\,\,cm\] \[\therefore \,\,\,\,\,\,\,\,\,\,\,\,Volume=\frac{22}{7}\times 9\times 14\]                        \[=396\,\,\,c{{m}^{3}}\]
