Is the radian always equal to the radius of a circle?

Is the radian of a circle always equal to the radius of a circle? If so, are there always the same number of radians in every circle? If an angle has a measure of 30 degrees, the radian would be around .52. Does that mean that the radius is .52?

Respectfully, a radian is the measure of a central angle that subtends an arc on the circle that is equal to the radius

True.  But Jordan seems to be asking that if the radian measure of an angle is x, then is the radius of the circle also x?  That is definitely not true.  At least that's my take on what is being asked.
