    A solid metallic cylinder of base 3 cm and height 5 cm is melted to make n solid cones of height 1 cm and base radius 1 mm. The value of n is

    A) 450      

    B)  1350

    C)  4500   

    D)  13500

    Correct Answer: D

    Solution :

    Number of cones \[\text{=}\frac{\text{Volume}\,\,\text{of}\,\,\text{solid}\,\,\text{cylinder}}{\text{Volume}\,\,\text{of}\,\text{1}\,\,\text{cone}}\] \[=\frac{\pi \times 3\times 3\times 5}{\frac{1}{3}\pi \times \frac{1}{10}\times \frac{1}{10}\times 1}=13500\]
