Now to find how many radians are in a complete circle; we must know how many radii make the circumference of the circle. So, if the length of the circumference of the circle is divided on the length of the radius of the circle, we will get the number of radii included in the circumference of the circle. Obviously, that number will be the number of radians included in (or account for) the circumference of the circle. Hence, if C is the circumference of the circle, we know that,

Great sir 👌
