Answer:

Volume of the sphere is
$972\pi\ cm^(3)$ .

Option (b) is correct .

Explanation:

Formula

$Volume\ of\ a\ sphere = (4)/(3) \pi r^(3)$

Where r is the radius of a circle .

As given

Sphere with a radius of 9 .

r = 9m

Putting all the values in the formula

$Volume\ of\ a\ sphere = (4)/(3) \pi* 9* 9* 9$

$Volume\ of\ a\ sphere = (4* 9* 9* 9)/(3) \pi$

$Volume\ of\ a\ sphere = (2916)/(3) \pi$

$Volume\ of\ a\ sphere = 972\pi\ cm^(3)$

Therefore the volume of the sphere is
$972\pi\ cm^(3)$ .

Option (b) is correct .
