matlab code error help

x = r*cospi*cos(theta);
y = r*cospi*sin(theta);
z = r*sinpi;
r = sqrt(x^2+y^2+z^2);
theta = atan*(y/x);
pi = atan*(z/sqrt(x^2+y^2));
'r' is an unrecognized function or variable.
can you tell me how can write r?

Clearly you haven't defined the variables r and theta and you are using them in the first three equations.

As a suggestion you can refer to Symbolic Computations in MATLAB & Create Symbolic Numbers, Variables, and Expressions.
