ANSWER
[tex]V=3052.08ft^3[/tex]
EXPLANATION
We want to find the volume of the sphere.
The volume of a sphere is given as:
[tex]V=\frac{4}{3}\cdot\pi\cdot r^3[/tex]
where r = radius of the sphere.
Therefore, we have that the volume of the sphere is:
[tex]\begin{gathered} V=\frac{4}{3}\cdot3.14\cdot9^3 \\ V=3052.08ft^3 \end{gathered}[/tex]
That is the volume of the sphere.
