Answer:
C. 81π cm³
Explanation:
The volume of the cylinder is found using the volume formula:
V = πr²h
where r is the radius and h is the height.
__
application
For the cylinder shown, the radius is r = 3 cm, and the height is h = 9 cm. Then the volume is ...
V = πr²h = π(3 cm)²(9 cm) = 81π cm³ . . . . matches choice C
