Final answer:
The volume of the cylinder is 9.28 cm³.
Step-by-step explanation:
To find the volume of a cylinder, you can use the formula V = πr²h, where V is the volume, r is the radius, and h is the height. In this case, the radius is 18 millimeters (0.75 cm) and the height is 18 millimeters (5.25 cm).
Plugging in the values, we get:
V = 3.142 × (0.75 cm)² × 5.25 cm = 9.278 cm³
Rounding to the nearest hundredth, the volume of the cylinder is approximately 9.28 cm³.
