From the Red Book:

#define PI 3.1415926535898
GLint circle_points = 100;
glBegin(GL_LINE_LOOP);
for (i = 0; i < circle_points; i++) {
angle = 2*PI*i/circle_points;
glVertex2f(cos(angle), sin(angle));
}
glEnd();

You can also use:
#include <cmath>
and then the constant M_PI which is defined in cmath.h
