A) 3 : 6 : 1
B) 3 : 4 : 1
C) 3 : 2 : 1
D) 4 : 3 : 1
Correct Answer: A
Solution :
If the radius of the hemisphere be r units, then height of cylinder and cone = r units \[\therefore \] Required ratio \[=\pi {{r}^{2}}h:2\pi {{r}^{3}}:\frac{1}{3}\pi {{r}^{2}}h\] \[=\pi {{r}^{3}}:2\pi {{r}^{3}}:\frac{1}{3}\pi {{r}^{3}}\] \[=3\,\,:\,6:1\]You need to login to perform this action.
