Given:
Given that the radius of the sphere is 9 cm
We need to determine the volume of the sphere.
Volume of the sphere:
Let us determine the volume of the sphere.
The volume of the sphere can be determined using the formula,
[tex]V=\frac{4}{3} \pi r^3[/tex]
where r is the radius of the sphere.
Substituting r = 9 in the above formula, we get;
[tex]V=\frac{4}{3} \pi (9)^3[/tex]
[tex]V=\frac{4}{3} \pi (729)[/tex]
[tex]V=\frac{2916}{3} \pi[/tex]
[tex]V=972 \pi[/tex]
Thus, the volume of the sphere is 972π cm³
Hence, Option B is the correct answer.
