I completed the first small step of the goal myself.
Use the following code to draw a circle (the first circle given in the title)
The second step is how to draw two circles into the same coordinate system?
syms x y r
x = -1 ;
y = 0;
r = 1;
rectangle('Position',[x-r,y-r,2*r,2*r],'Curvature',[1,1],'EdgeColor','m')
