Points on the edge of the disk represent solutions to |z| = 6, while points inside the disk are solutions to |z| < 6.
Assuming there isnt a line under the less than sign, then you'll have a dashed boundary to indicate points on the boundary do not count. If you want the boundary points to count, then you'll have to write
Diagram:
The blue region is the solution to . The red dashed boundary is not part of .
The equation of the red boundary circle is
The inequality for the blue region is
Note: recall that for any complex number , the magnitude of the complex number is (it might help to plot an example complex number on the xy plane, draw a right triangle, then apply the pythagorean theorem)
