Answer:
Step-by-step explanation:
The picture of the question in the attached figure
we know that
The volume of a cone is given by the formula
[tex]V=\frac{1}{3}\pi r^{2}h[/tex]
we have
[tex]h=2x\ units\\r=x\ units[/tex]
substitute
[tex]V=\frac{1}{3}\pi x^{2}(2x)[/tex]
[tex]V=\frac{2}{3}\pi x^{3}\ units^3[/tex]
