I am doing a code to calculate the circumference and area of a circle, but when I get the results, the answer is the circumference and area are reversed, I don't know where I am wrong?
r = input('r= ');
P = pi * 2 * r;
S = pi * (r^2);
fprintf('P = %.2f\n',S);
fprintf('S = %.2f\n',P);

You just need to change the arguments in fprintf, since you must have accidentally swapped them.
r = 1;
P = pi * 2 * r;
S = pi * (r^2);
fprintf('P = %.2f\n',P);
fprintf('S = %.2f\n',S);
