User input changes circle radius and velocity

I want to make this so that when a user inputs a new radius, the circle changes accordingly, but I'm not sure how to go about it.
v=input('Please provide a particle velocity: \n');
r=input('Please provide a radius: \n');
x0 = 0;
y = 3;
for time=-7:0
x = x0(1,:) + v*time;
plot(x, y,'ro'); % particle moving along the x axis
axis([-3 3 -7 3])
drawnow();
pause(.5)
end
t = linspace(0,2*pi);
x = cos(t);
y = sin(t);
plot(3*x,3*y) % current plot circle - radius 10
axis equal
hold on
for t0 = t
h = plot(3*sin(t0),3*cos(t0),'or'); % particle moving around the circle
pause(0.3)
delete(h)
end
hold off

You are using the radius while calculating the coordinates of circle.
v=input('Please provide a particle velocity: \n');
r=input('Please provide a radius: \n');
x0 = 0;
y = 3;
for time=-7:0
x = x0(1,:) + v*time;
plot(x, y,'ro'); % particle moving along the x axis
axis([-3 3 -7 3])
drawnow();
pause(.5)
end
t = linspace(0,2*pi);
x = r*cos(t); % use the radius here
y = r*sin(t); % use the radius here
plot(x,y) % current plot circle - radius 10
axis equal
hold on
for t0 = t
h = plot(3*sin(t0),3*cos(t0),'or'); % particle moving around the circle
pause(0.3)
delete(h)
end
hold off

v=10;%input('Please provide a particle velocity: \n');
r=5; %input('Please provide a radius: \n'); e.g. radius here
x0 = -2; % offset
y0 = 3; % offset
t = linspace(0,2*pi);
x = x0 + r*cos(t); % use the radius here with an offset
y = y0 + r*sin(t); % use the radius here with an offset
plot(x,y) % current plot circle
x = r*cos(t); % use the radius here without an offset
y = r*sin(t); % use the radius here without an offset
hold on
plot(x,y,'r')
you can also try using an offset distance for centre to plot
