Answer:
28.27 cubic units
Explanation:
The volume is given by the formula ...
V = πr²h
Here, the radius (r) is half the diameter, so is 1.5. The height (h) is 4, so the volume is ...
V = π(1.5²)(4) = 9π
Using the "pi button" on the calculator, the volume is ...
V = 28.27 cubic units
_____
If you use 3.14 for π, you get 28.26 cubic units.
