A radian is the SI unit for measuring angles. It is defined as the angle subtended at the center of a circle by an arc whose length is equal to the radius of the circle. One complete revolution is equal to 2π radians.
A radius is a line segment extending from the center of a circle or sphere to any point on its circumference or surface. It also refers to the length of this segment.
