    If the height and diameter of a right circular cylinder are 32 cm and 6 cm respectively, then  the radius of the sphere whose volume is equal to the volume of the cylinder is

    A) 3 cm    

    B)  4 cm

    C)  6 cm   

    D)  8 cm

    Correct Answer: C

    Solution :

    Volume of sphere = Volume of cylinder \[\therefore \]      \[\frac{4}{3}\pi {{R}^{3}}=\pi \times 3\times 3\times 32\] \[\Rightarrow \]   \[{{R}^{3}}=3\times 3\times 3\times 8\] \[\Rightarrow \]   \[R=6\,\,\text{cm}\]
