A) \[770\,c{{m}^{3}}\]
B) \[1000\,c{{m}^{3}}\]
C) \[1540\,c{{m}^{3}}\]
D) \[6622\,c{{m}^{3}}\]
Correct Answer: A
Solution :
| [a] \[r=7\,cm\]and \[2\pi rh=220\] \[\Rightarrow \] \[2\times \frac{22}{7}\times 7\times h=220\] \[\Rightarrow \] \[h=5\,cm\] Volume \[=\pi {{r}^{2}}h=\left( \frac{22}{7}\times 7\times 7\times 5 \right)\,c{{m}^{3}}\] \[=770\,c{{m}^{3}}\] |
