The easiest approach would be to use the rectangle function with the curvature option to make circles and to fill all of them.
Plot them in order from bottom to top with the top most circle being white.

Hello Gabriel Malagon Carvajal. You can try this:
%k is a constant that you can difine as the circles size
k = 0.4 %a exemplo of a 0.4 diamater circle
theta = linspace(0,2*pi);
rho = k*sin(theta);
polarplot(theta,rho)

You can change the values of radius, x_center and y_center:
radius = 1;
x_center = 0.5;
y_center = 0.5;
th = 0:pi/50:2*pi;
xunit = radius * cos(th) + x;
yunit = radius * sin(th) + y;
[theta,rho] = cart2pol(xunit,yunit)
polarplot(theta,rho)
