Answer:
16π cubic units
Step-by-step explanation:
The volume of a cylinder can be calculated using the formula V = πr^2h, where r is the radius of the base and h is the height of the cylinder.
Given that the base has a diameter of 4, the radius is half of the diameter, so the radius (r) is 2.
Using the formula, V = π(2)^2(4), we can now calculate the volume:
V = π(4)(4)
V = 16π
Therefore, the volume of the cylinder is 16π cubic units.
