A) \[16\,\pi \,\,c{{m}^{3}}\]
B) \[12\,\pi \,\,c{{m}^{3}}\]
C) \[15\,\pi \,\,c{{m}^{3}}\]
D) \[20\,\pi \,\,c{{m}^{3}}\]
Correct Answer: A
Solution :
\[\because \] \[h=3\,cm,\] and \[r=4\,cm\] \[\therefore \] Volume of cone\[=\frac{1}{3}\pi {{r}^{2}}h\] \[=\frac{1}{3}\pi \times 16\times 3=16\pi \,c{{m}^{3}}\]
