Two codes becoming one

Hello Family,
Please I need to create three circles. Challenge One: Circle 1 is small and going round on the circumference of circle 2. Challenge 2: Circle 2 is nearly as big as circle 3. Circle 2 is the inner circle with close diameter with circle 3. Circle 2 is going round inside circle 3. I have the codes for challenge One and challenge Two individually...the problem is to make the two codes work as one.
Challenge One Codes:
r=18;
R=20;
radius=[r R]
velocity=[45 0]
colors=['c','r'] % This is to just make the points different colors
p=zeros(2,1); %here we will store the handles to delete the point
hold on
for i=1:2 %Loop to create multiple circles
th=0:pi/50:2*pi;
xunit=radius(i)*cos(th);
yunit=radius(i)*sin(th);
h=plot(xunit,yunit);
p(i)=plot(xunit(1),yunit(1),'o','MarkerFaceColor',colors(i),'Color',colors(i));
%creates a point on each graph
end
time=[0:0.001:100]; %time vector in seconds
for t=1:length(time)
for i=1:2 %Loop to create multiple circles
delete(p(i)); %delete the old point
%computes the new angle for each point as velocity*time
xunit=radius(i)*cos(velocity(i)*time(t));
yunit=radius(i)*sin(velocity(i)*time(t));
%creates a point on each graph
p(i)=plot(xunit(1),yunit(1),'o','MarkerFaceColor',colors(i),'Color',colors(i));
end
pause(0.01); %wait 0.01 seconds so the plot is displayed
end
hold off
Challenge Two Codes
t = linspace(0,5*pi );
x = cos(t );
y = sin(t );
plot(7*x,7*y)
axis equal
hold on
for t0 = t
h = plot(2*sin(t0),2*cos(t0),'or ','markersize',175);
pause(0.09 )
delete(h )
axis equal
end

@DARLINGTON: it doesn't motivate people to help you if you respond with a flag instead of a comment. Also, your tone seems quite aggressive. It is on you to make clear what the essence of your question is. Most people on this forum prefer helping two people that have a clear question instead of spending the same time on one question that isn't as clear.
Because I don't see how this question is different from your previous one, I don't see a reason not to close it. Feel free to re-open and edit your question. When you do, make sure to the tools explained on this page to make your question more readable.
