Final answer:
The volume of a cylinder with a height of 9 cm and a base diameter of 4 cm is approximately 113.1 cm³ when rounded to the nearest tenths place.
Step-by-step explanation:
The volume of a cylinder can be calculated using the formula V = πr²h, where V is the volume, r is the radius, and h is the height of the cylinder. For a cylinder with a height of 9 centimeters and a base diameter of 4 centimeters, first find the radius by dividing the diameter by 2, giving us a radius of 2 centimeters. Plugging the values into the formula yields V = π * 2² * 9, which calculates to approximately 113.1 cm³ when rounded to the nearest tenths place.
