volume = $3017.142857143 m^{3}$ $3017.142857143 m^3$

Explanation:

the volume of a cone equals to the one third of the volume of a cylinder.
therefore volume of a cone $= \frac{1}{3} \cdot π r^{2} h$ $= 1/3 *pi r^2 h$ where $r$ $r$ is the radius of the circular base of the cone and $h$ $h$ is the height.

assign the values to the respective places

volume = $\frac{1}{3} \cdot \frac{22}{7} \cdot 12^{2} \cdot 20 m^{3}$ $1/3* 22/7* 12^2*20 m^3$
volume = $3017.142857143 m^{3}$ $3017.142857143 m^3$
