ANSWER
[tex]134.04\text{ cubic units}[/tex]EXPLANATION
The volume of a hemisphere is given by:
[tex]V=\frac{2}{3}\pi r^3[/tex]where r = radius
Hence, the volume of the given hemisphere is:
[tex]\begin{gathered} V=\frac{2}{3}*\pi *4^3 \\ V=134.04\text{ cubic units} \end{gathered}[/tex]That is the answer.
