    A sphere of radius 4 cm has the same volume as that of a cone with a circular base of radius 4 cm. The height of the cone is

    A)  12 cm            

    B)         16 cm  

    C)  20 cm                  

    D)  24 cm

    Correct Answer: B

    Solution :

     Let the height of the cone be h. But Volume of cone= volume of sphere \[\therefore \] \[\frac{1}{3}\pi \times {{4}^{2}}\times h=\frac{4}{3}\pi \times {{4}^{3}}\] or            \[h=16\,cm\]
