A) \[5544\,c{{m}^{3}}\]
B) \[3465\,c{{m}^{3}}\]
C) \[7720\,c{{m}^{3}}\]
D) \[13860\,c{{m}^{3}}\]
Correct Answer: D
Solution :
Circumference of base \[=66\,cm,\] \[\therefore \] \[2\pi r=66\] \[\Rightarrow \] \[r=\frac{66\times 7}{2\times 22}=\frac{21}{2}cm\] and height of cylinder \[=40\,cm\] \[\therefore \] Volume of cylinder \[=\pi {{r}^{2}}h\] \[=\frac{22}{7}\times \frac{21}{2}\times \frac{21}{2}\times 40\] \[=13860\,c{{m}^{2}}\]
