A) \[235\text{ }{{m}^{3}}\]
B) \[~456\text{ }{{m}^{3}}\]
C) \[365\text{ }{{m}^{3}}\]
D) \[~462\text{ }{{m}^{3}}\]
Correct Answer: D
Solution :
Circumference of the base of cone =circumference of circle \[=2\pi r\] \[\Rightarrow \]\[44=2\pi r\Rightarrow r=7m\] Volume of the cone \[=\frac{1}{3}\pi {{r}^{2}}h\] \[=\frac{1}{3}\times \frac{22}{7}\times {{(7)}^{2}}\times 9=462\,{{m}^{3}}\] Hence, the volume of \[462\,{{m}^{3}}\]
