Answer:

Option B is correct i.e v= 972[tex]\pi[/tex] [tex]m^{3}[/tex]

Step-by-step explanation:

If radius of sphere = 9

for volume of sphere

The formula used will be

[tex]v= \frac{4}{3} \pi r^{3}[/tex]

as r = 9

[tex]v = \frac{4}{3} \pi (9)^{3}[/tex]

[tex]\\v= \frac{4}{3} (729)\pi \\v= \frac{(729 \times 4)}{3} \pi \\v=\frac{2916}{3} \pi \\v=972 \pi[/tex]

So v= 972[tex]\pi[/tex] [tex]m^{3}[/tex]
