A) \[32\text{ }cm\]
B) \[24\text{ }cm\]
C) \[48\text{ }cm\]
D) \[\text{54 }cm\]
Correct Answer: D
Solution :
Height of the right circular conical flask =18 cm. Let the radius of right circular cone is r cm, and height of the water in cylindrical flask is h cm. So, Volume of water in conical flask = Volume of water in cylindrical flask \[\frac{1}{3}\,\,\pi {{r}^{2}}\times 18=\frac{\pi {{r}^{2}}}{9}\times h\] \[h=\frac{18\times 9}{3}=\underline{\mathbf{54}\,\mathbf{cm}\mathbf{.}}\]
