Webradian: [noun] a unit of plane angular measurement that is equal to the angle at the center of a circle subtended by an arc whose length equals the radius or approximately 57.3 degrees. WebThe measurements of the central angle can be given in degrees or radians, and accordingly, we calculate the arc length of a circle. If θ is in radians, then the angle in degrees = θ × 180/π. By substituting this in the above formula, Arc length = rθ × π/180 × 180/π = rθ. hawk inn and mountain resort news
