The volume of a cylinder is given by πr²h, where r is its radius and h is its height.
By substituting the height and volume that you're given, you can say that 320π = 3.2πr².
From there, you just solve to find r.
To do that, you'd get r² on its own and then take the square root of both sides.
Why did the vector cross the road?
It wanted to be normal.
