A) 22 cubic m
B) 36 cubic m
C) 40 cubic m
D) 44 cubic m
Correct Answer: D
Solution :
Let h be the height of water level which will be dropped. \[\therefore \] \[11=\pi {{\left( \frac{35}{2} \right)}^{2}}\times h\] \[\Rightarrow \] \[11000=\frac{22}{7}\times \frac{35}{2}\times \frac{35}{2}\times h\] \[\Rightarrow \] \[h=\frac{11000\times 7\times 2\times 2}{22\times 35\times 35}=11\frac{3}{7}\,cm\]You need to login to perform this action.
