Answer: The three-dimensional shape that would result would be in the shape of a donut. 

Imagine taking a knife and cutting a slice in a donut. The cross-section of where you cut would be a circle. This is what would happen if you rotated the circle around the y-axis. It would be like that cross-section of the donut going around the entire circle.
