The volume of a Cone.
[tex]\begin{gathered} \text{Volume = }\frac{1}{3}\times\pi r^2h \\ \text{Where r =radius=}\frac{10}{2}=5\text{cm , h =height=}12\operatorname{cm} \end{gathered}[/tex]Substituting these values in the above formula, we get,
[tex]\text{Volume =}\frac{1}{3}\times\pi\times5^2\times12=\frac{(12)5^2\pi}{3}[/tex]Hence,
The correct answer is
