A) \[54\,\pi \,cu\,cm\]
B) \[36\,\pi \,cu\,cm\]
C) \[6.054\,\pi \,cu\,cm\]
D) \[6.54\,\pi \,cu\,cm~\]
Correct Answer: A
Solution :
Circumference of base \[=6\pi \] \[\Rightarrow \] \[2\pi r=6\pi \] \[\Rightarrow \] \[r=3\,cm\] \[\therefore \] Height of the cylinder \[=6\,cm\] \[\therefore \] Volume of cylinder \[=\pi {{r}^{2}}h\] \[=\pi \times 3\times 3\times 6\] \[=54\,\pi \,cu\,cm\]
