A) 1:2
B) 2:3
C) 3:4
D) 4:5
Correct Answer: A
Solution :
[a] Volume of cone, \[C=\frac{1}{3}\pi {{R}^{2}}H\] \[=\frac{1}{3}\pi {{R}^{3}}\] \[(\therefore \,\,\,H=R)\] Volume of hemisphere, \[H=\frac{2}{3}\pi {{R}^{3}}\] .\[\therefore \,\,C\,\,:\,\,H=\frac{1}{3}\pi {{R}^{3}}:\,\,\frac{2}{3}\pi {{R}^{3}}=1:2\]You need to login to perform this action.
