Explanation:
We know that the volume of a cylinder is given by :-
![\text{Volume}=\pi r^2 h](https://img.qammunity.org/2019/formulas/mathematics/middle-school/tsrj4vhq54uyqhny0tv8shwutd0f91boyu.png)
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 :-
![\text{Volume}=\pi (8)^2 (3)=\\\\\Rightarrow\text{Volume}=192\pi\text{ units}^2](https://img.qammunity.org/2019/formulas/mathematics/college/qh5qgyx89jiknbxm42sjwnlu4iagtsor96.png)
Hence, the volume of the given cylinder :
