Volume of a cylinder is:
π x radius² x height
Radius = width / 2 = 2
so:
π x 2² x 8 = 32π = 100.53
I'm guessing the answer is "32in" because that's the only answer that matches the answer 32π. Maybe the units are wrong in the question.
Since the equation has a absolute value in it, the equation will be reflected over the axis of symmetry, which just so happens to be the y-axis in this case. (The answer is c).
The number goes on and on so put a line on top of that num. To show it teacher that,that number is infinite. So yeah ur right (°∀°)b
