What is the volume of this sphere?

Answer:
The volume of the sphere is 972π m³
B is correct
Step-by-step explanation:
Given: We are given a figure of sphere whose radius is 9 m
Formula:
[tex]\text{Volume of sphere}=\dfrac{4}{3}\pi r^3[/tex]
where, r=9 m
Substitute r=9 into formula to get volume of sphere
[tex]\text{Volume of sphere}=\dfrac{4}{3}\pi 9^3[/tex]
[tex]=\dfrac{4}{3}\pi \times 9\times 9\times 9[/tex]
[tex]=4\pi \times 3\times 9\times 9[/tex]
[tex]=972\pi \text{ m}^3[/tex]
Hence, The volume of the sphere is 972π m³
