    The material of a solid cone is converted into the shape of a solid cylinder of equal radius. If the height of the cylinder is 5 cm, what is the height of the cone?

    A)  \[15\text{ }cm\]                        

    B)  \[\text{20 }cm\]

    C)  \[\text{25 }cm\]                        

    D)  \[\text{30 }cm\]

    Correct Answer: A

    Solution :

    In this case : Volume of cone = Volume of cylinder \[\frac{1}{3}\pi {{r}^{2}}h=\pi {{r}^{2}}\times 5\Rightarrow h=15\ cm\] \[\therefore \]   Height (h) of cone = 15 cm
