Answer:
16π cm²
Explanation:
The volume of a cylinder is denoted by: V = πr²h, where r is the radius and h is the height. And, πr² is the area of the base.
Here, we know the volume is V = 144π and the height is h = 9, so plug these in:
V = πr²h
144π = πr² * 9
Divide both sides by 9:
πr² = 144π/9 = 16π
So the area is 16π cm².
