To find the volume of a cone, you can use the formula:
\[ V = \frac{1}{3} \pi r^2 h \]
where \( V \) is the volume, \( r \) is the radius of the base, and \( h \) is the height of the cone. From your information, the height (\( h \)) is 12 mm. However, you did not provide the radius (\( r \)).
Assuming you have the radius, please provide that value to calculate the volume correctly.
