Answer: D.
The radius is 11 units, and the volume is 5,572.45 cubic units.
Step-by-step explanation:
We know that the volume of a sphere is given by :-
[tex]\text{Volume}=\dfrac{4}{3}\pi r^3[/tex], where r is radius of the sphere.
Given : The diameter of the sphere = 22 units
Then the radius of the sphere = [tex]\dfrac{22}{2}=11\text{ units}[/tex]
Then , the volume of the sphere will be :-
[tex]\text{Volume}=\dfrac{4}{3}(3.14)(11)^3\\\\\Rightarrow\ \text{Volume}=5572.45 \approx\text{ cubic units}[/tex]
Hence, the volume of the sphere = 5,572.45 cubic units
