Plotting points inside a circle

This is probably a very simple question, I’m new to MatLab and I’ve always really used Python. I need to plot a set of points (position of a chemical inside a nucleus) inside a circle of radius 5. How would you go about this? I can plot the circle, and I have the coordinates (polar) of the points, I just can’t add those points.

[Walter Roberson]

maxr = 5;

%create data
N = 20;
r = rand(1,N) * maxr;
theta = rand(1,N) * 2*pi;

[x, y] = pol2cart(theta, r);

%plot

scatter(x, y, 'b*');
hold on
viscircles([0 0], maxr);
hold off
axis equal
