How do i end my code

How do i end my code even though I got the answer already? this is the code

function circular
r = input("Enter the Radius: ");
disp("Circumference is ");
disp(2*pi*r);

disp("Area is ");
disp(pi*r*r);

disp("Volume is ");
disp((4*pi*r*r*r)/(3));
end


THERE IS AN EXAMPLE OF MY PROBLEM IN THIS CODE
Enter the Radius: 
1
Circumference is 
    6.2832

Area is 
    3.1416

Volume is 
    4.1888

Enter the Radius: (it still asks me to enter an input)

How do you call this function?

this is actually only a part of the entire code im making since it's a menu driven code

You have showed some code, which runs once only. The output shows, that this function is called again afterwards, but we do not see, from where. But there is the point to modify your program.

The loop in the calling code might look like this:

function main
while 1
    circular
end
end

Then modify this loop and insert a test inside the function, if an invalid input is chosen:

function main
proceed = true;
while proceed
   proceed = circular;
end
end

function proceed = circular
r = input("Enter the Radius (hit return to stop: ");
proceed = ~isempty(r);
if ~proceed  % Stop and reply FALSE
   return;
end
disp("Circumference is ");
disp(2*pi*r);
disp("Area is ");
disp(pi*r*r);
disp("Volume is ");
disp((4*pi*r*r*r)/(3));
end
