7.2 Radian Measure


Radian

Radian

Units of measure for angles:

revolution, degree, & radian

Radian: a central angle has measure 1 radian if it intercepts an arc with length equal to the radius of the circle

r

r

 = 1 radian

r


Converting

Converting

1 revolution = 360 = 2 radians

(Circumf. of Circle = 2r)

 radians = 180

radians → degrees, multiply by

degrees→ radians, multiply by


Examples

Examples

Leave radian measure in terms of 

May omit word “radians”


Example 3

Example 3

(round to 4 dec. places)

Change to decimal degrees

Change to radians
