A) \[1223\,c{{m}^{2}}\]
B) \[~1232\,c{{m}^{2}}\]
C) \[~1323\,c{{m}^{2}}\]
D) \[1332\,c{{m}^{2}}\]
Correct Answer: B
Solution :
\[T.S.A=\frac{3520}{5}=704\,c{{m}^{2}}\] \[\Rightarrow \]\[\pi r(l+r)=704\Rightarrow r=7\] \[\Rightarrow \]\[h=\sqrt{{{l}^{2}}-{{r}^{2}}}=24\] \[V=\frac{1}{3}\pi {{r}^{2}}h\] \[=\frac{1}{3}\times \frac{22}{7}\times 7\times 7\times 24=1232\,c{{m}^{3}}\]You need to login to perform this action.
