A) \[1:4\]
B) \[3:4\]
C) \[4:3\]
D) \[2:3\]
Correct Answer: C
Solution :
(c): As the cylinder and cone have equal diameters. So they have equal area. Let cone?s height be \[{{h}_{2}}\] and as per question, cylinder?s height be \[{{h}_{1}}\] \[\frac{2\pi r{{h}_{1}}}{\pi r\sqrt{h_{2}^{2}+{{r}^{2}}}}=\frac{8}{5}\] and put \[{{h}_{1}}=r\] The desired ratio is \[4:3\]You need to login to perform this action.
