A) \[8.325\,\,{{m}^{3}}\]
B) \[9.725\,\,{{m}^{3}}\]
C) \[12.32\,\,{{m}^{3}}\]
D) \[8.675\,\,{{m}^{3}}\]
Correct Answer: C
Solution :
Curved surface \[=2\pi rh\]and perimeter\[=2\pi r\] \[\therefore \]\[17.6=8.8\times h\] or, \[h=2\,\,m\]. \[\because \] \[2\pi r=8.8\] \[\therefore \] \[r=\frac{8.8\times 7}{2\times 22}=1.4\,\,m\] \[\therefore \] Volume\[=\pi {{r}^{2}}h\] \[=\frac{22}{7}\times 1.4\times 1.4\times 2\] \[=12.32\,\,{{m}^{3}}\]You need to login to perform this action.
