Find the volume of the sphere. Express your answer in terms of π.



A: 2,916π cm3


B: 972π cm3


C: 108π cm3


D: 324π cm3

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=(4)/(3) \pi r^3`

where r is the radius of the sphere.

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

`V=(4)/(3) \pi (9)^3`

`V=(4)/(3) \pi (729)`

`V=(2916)/(3) \pi`

`V=972 \pi`

Thus, the volume of the sphere is 972π cm³

Hence, Option B is the correct answer.
