No, what it did is that it did not work as you expected. You are always erasing the previous plot if you do not use hold on. And even if you did, you would have plotted some points, not a line.
Please accept an answer if it helped you. Please look at the documentation on the plot function
doc plot
doc hold

x = 0.2:0.01:0.6;
y = 4*(sqrt(1-x.^2))./(2*pi*x);
plot(x,y)
You should always post your code.

What does "it ain't working" mean?
x= [ 0.2 :0.1 : 0.6 ] ;
y = 4 * (sqrt(1 - x.^2)) ./ (2*pi.*x);
plot(x,y);
