The diagram shows how the value of the function (y) is calculated from the radius (a - red) of the circle sweeping out an angle θ (theta). What does "sweeping out an angle" mean here?

The sweep of an angle would be something similar to this. It's the angle produced by the rotation of the line from the center to the edge of the circle around the circumference.
