1 radian = _____ degrees.
- A
360

180
- C
100
- D
57.3
- E
1.01745
Radian is the SI unit of measuring angles. It is the measure of the central angle whose arc length is the same as the radius of the circle.
In one circle,
2π radians =360
1 radian is equal to 180/π degrees, which is approximately 57.3°
This is incorrect. 360 degrees represents the total degrees in a full circle, not the conversion for 1 radian.
This is incorrect. 180 degrees is half of a full circle, not the conversion for 1 radian.
This is incorrect. 100 degrees is not related to the conversion between radians and degrees.
This is correct. 1 radian is approximately equal to 57.3 degrees.
This is incorrect. 1.01745 radians is not the conversion to degrees but rather another value in radians.
