A) \[66\,c{{m}^{3}}\]
B) \[77\,c{{m}^{3}}\]
C) \[88\,c{{m}^{3}}\]
D) \[121\,c{{m}^{3}}\]
Correct Answer: B
Solution :
Circumference of base of cylinder \[=11\,cm\] \[\therefore \] \[2\pi r=11\] \[\Rightarrow \] \[r=\frac{11\times 7}{22\times 2}=\frac{7}{4}cm\] and height of cylinder \[=8\,cm\] \[\therefore \] Volume of cylinder \[=\pi {{r}^{2}}h\] \[=\frac{22}{7}\times \frac{7}{4}\times \frac{7}{4}\times 8=77\,c{{m}^{3}}\]
