Answer
C. 1230.88 mm cubed
Step-by-step explanation
Volume of a cylinder formula
[tex]V=\pi r^2h[/tex]
where r is the radius and h is the height of the cylinder.
Substituting r = 7 mm and h = 8 mm, we get:
[tex]\begin{gathered} V=\pi\times7^2\operatorname{\times}8 \\ V\approx3.14\times49\operatorname{\times}8 \\ V\approx1230.88\text{ mm}^3 \end{gathered}[/tex]
