Answer: 400 meters cubed
Step-by-step explanation:
The volume of cylinder is given by :-
[tex]\text{Volume of cylinder}=\pi r^2 h[/tex], where r is radius and h is height of the cylinder.
The volume of cone is given by :-
[tex]\text{Volume of cone}=\dfrac{1}{3}\pi r^2 h[/tex], where r is radius and h is height of the cone.
When they both have the same radius and height, then we have
[tex]\text{Volume of cone}=\dfrac{1}{3}\times[\text{Volume of cylinder}]\\\\\Rightarrow\ \text{Volume of cone}=\dfrac{1}{3}\times1200\\\\\Rightarrow\ \text{Volume of cone}=400 \text{ meters cubed}[/tex]
