Radians vs Degrees Unit Circle Radians Examples Lesson Summary Frequently Asked Questions Why is it called a unit circle? A unit circle is a circle with a radius of 1 unit. The unit circle is often shown on a coordinate plane with its center at the origin. The circle will cross the x...
1 radian is equal to the angle subtended by an arc at the center of the circle whose length is equal to the radius of the circle. What is the Radians to Degrees Formula? To convert radians to degrees, we multiply the angle by 180/π. For example, 3π/2 = 3π/2 × 180/π = ...

Value in degree =31/2× 57.295779513082=200.535degrees Definition of Radian Radian describes the plane angle subtended by a circular arc as the length of the arc divided by the radius of the arc. One radian is the angle subtended at the center of a circle by an arc that is equal in leng...
The meaning of RADIAN is 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.
Radians into degreesDegrees into radians Coterminal angles The multiples of π IN THE RADIAN SYSTEM of angular measurement, the measure of one full circle is 2π.(In the next Topic, Arc Length, we will see the actual definition of radian measure.)...
A circle has {eq}2\pi {/eq} radians or 360°. Similarly, the angle measure of a straight line is {eq}\pi {/eq} radians or 180°. Using this equivalency, conversion between degrees and radians can be done using the following formula: {eq}\frac{\mathrm{rad}}{\pi}=\frac{\mathrm{...
