A) \[1:3\]
B) \[2:3\]
C) \[3:4\]
D) \[3:1\]
Correct Answer: C
Solution :
(c): Let the radius of cylinder = r Then, the radius of cone \[=R=2r\] \[\therefore \] \[{{\left( \frac{r}{R} \right)}^{2}}=\frac{1}{4}\] Then, as per question. Ratio \[=\frac{\pi {{r}^{2}}h}{\frac{\pi {{R}^{2}}h}{3}}=\frac{2\pi {{r}^{2}}h}{\pi {{R}^{2}}h}=\frac{3{{r}^{2}}}{{{R}^{2}}}=3:4\]You need to login to perform this action.
