What is the volume of the cylinder below?

Answer: D. [tex]192\pi\text{ units}^2[/tex]
Step-by-step explanation:
We know that the volume of a cylinder is given by :-
[tex]\text{Volume}=\pi r^2 h[/tex]
From the given picture, we have the radius of cylinder = 8 units
and the height of cylinder = 3 units
Then the volume of the given cylinder will be :-
[tex]\text{Volume}=\pi (8)^2 (3)=\\\\\Rightarrow\text{Volume}=192\pi\text{ units}^2[/tex]
Hence, the volume of the given cylinder :[tex]192\pi\text{ units}^2[/tex]
