I want to multiple circles with same center but different radius. Later on I want add a line from center that will intersect all the cirles. I am attaching a figure to demonstrate how will be my expected output.

Try this:
t = linspace(0, 2*pi);
r = [1, 2, 3];
xc = 0.5;
yc = 0.1;
xcir = (r(:)*cos(t))' + xc;
ycir = (r(:)*sin(t))' + yc;
figure
hold all
plot(xcir, ycir)
plot([xc, xc+5], [yc, yc], '-r')
hold off
axis equal
text(xc+r, yc*ones(1,numel(r)), ['$\frac{D}h$', compose('$\\frac{%dD}h$', r(2:end))], 'HorizontalAlignment','left', 'VerticalAlignment','top', 'Interpreter','latex', 'FontSize',12)
producing:
Experiment to get the result you want.
