A) 25%
B) 64%
C) \[\frac{200}{3}%\]
D) \[\frac{500}{3}%\]
Correct Answer: C
Solution :
\[\frac{1}{3}\pi {{r}^{2}}h=\frac{1}{3}\pi {{R}^{2}}\left( \frac{36}{100}h \right)\] \[\Rightarrow \,\,R=\frac{5}{3}r\] Increase m original radius \[=\frac{5}{3}r-r=\frac{2}{3}r\] \[=\frac{200}{3}%r.\]You need to login to perform this action.
