Answer:
True
Step-by-step explanation:
we know that
The volume of a cone is equal to
[tex]V=\frac{1}{3}BH[/tex]
where
B is the area of the base
H is the height of the cone
we have
[tex]B=7\ in^{2}[/tex]
[tex]H=9\ in^{2}[/tex]
substitute
[tex]V=\frac{1}{3}(7)(9)[/tex]
[tex]V=21\ in^{3}[/tex]
therefore
The answer is True
