Radian, английский
- A unit of angular measure equal to the angle subtended at the center of a circle by a chord whose length is equal to the radius of the circle.
- The angle between two radii of a circle such that the length of the arc between them is equal to the radius. the circumference of a circle is equal to 2p times the radius, so one radian contains 360/(2p) = 180/p = approximately 57.2958 degrees. conversely, multiplying the number of degrees by p/180 gives the number of radians; 360 degrees equals 2p radians. radio (n)
Flash lamp, английский
