Double-click the Line Tool to set the line width to the desired
thickness of the annular selection. Then convert your circle selection
to a line using 'Edit > Selection > Area to Line' and plot its profile.

In a macro:

makeOval(30, 30, 50, 50); // or draw a circle selection manually
setLineWidth(10);
run("Area to Line");
run("Plot Profile");

Hope that helps,
Jan
