In the International System of Units, the derived unit of plane angular measure of angle equal to the angle subtended at the centre of a circle by an arc of its circumference equal in length to the radius of the circle. Symbol: rad
A unit of plane angular measurement equal to the angle at the centre of a circle subtended by an arc equal in length to the radius Since the circumference of a circle is equal to 2p times its radius, the number of radians in an angle of 360 degrees or in a complete turn is 2p, so that 1 radian equals about 57 29 degrees
Unit of angular measure equal to 57 3°, the ratio of arc length to the radius of the circle
the unit of plane angle adopted under the Systeme International d'Unites; equal to the angle at the center of a circle subtended by an arc equal in length to the radius (approximately 57 295 degrees)
{i} central angle of an arc of any circle that is equal in length to the radius of the same circle (Mathematics)
The SI unit of plane angle One radian equals the angle subtended at the center of a circle by a circular arc which is equal in length to the radius of the circle
A unit of angular measurement The angle that, when placed with its vertex at the center of a circle, subtends on the circumference an arc equal in length to the radius of the circle Approximately 57 3o
A radian is a unit of angular measure equal to the angle subtended at the center of a circle by an arc of length equal to the radius of the circle equal to approximately 57 degrees, 17 minutes, 44 6 seconds
The angle subtended at the center of a circle by an arc equal in length to a radius of the circle It is equal to 360°/2π or approximately 57 degrees 17 minutes 44 8 seconds
A measure of angle; there are 2p radians in a circle The arc subtended by a radian is equal to the radius of the associated circle
A unit equal to the angle subtended at the center of a circle by an arc equal in length to the radius of the circle
Equal to the central angle subtended by an arc of unit length at the centre of a circle of unit radius
A radian is a unit arc, each having a length equal to the length of the circle's radius To find the angle Ø, in radians of a circle is equal to the length of the circle circumference divided by the radius of that circle; Ø = l ÷ r, this is rotational motion The circumference of a circle whose radius has a length r is r * 2; thus Ø = l ÷ r = 2 * r ÷ r = 2 = approximately 6 2831853072 radians 1 rad = 360 ÷ 6 28318530717959 = 57 2957795130823º = 57º 17 7467707849372 min or 57º 17 min and 44 8062470962331 sec or approximately 57º 18 min To convert from degrees to radians is: Rad (angle) = degrees (angle) * ÷ 180
Official unit of angular measurment in the metric (SI) system PI radians (3 1415 ) = 180°
