Answer 1

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,

$V=\frac{4}{3} \pi r^3$

where r is the radius of the sphere.

Substituting r = 9 in the above formula, we get;

$V=\frac{4}{3} \pi (9)^3$

$V=\frac{4}{3} \pi (729)$

$V=\frac{2916}{3} \pi$

$V=972 \pi$

Thus, the volume of the sphere is 972π cm³

Hence, Option B is the correct answer.
