Below are sample questions representative of the exercises included on this worksheet and related GEO.123 Radian measure and degree measure Answer Key skill assessments:

Problem 1Difficulty: Mastery
The diagram labels a smaller angle between two rays as 50 degrees. What is the radian measure of the reflex angle around the outside of the rays?
A5pi/18
B13pi/9
C31pi/18
D2pi
Solution & Explanation:The reflex angle is 360 - 50 = 310 degrees. Converting gives 310 x pi/180 = 31pi/18.
Problem 2Difficulty: Mastery
Convert 14pi/9 radians to degrees.
A240 degrees
B260 degrees
C280 degrees
D300 degrees
Solution & Explanation:(14pi/9)(180/pi) = 14 x 20 = 280 degrees.
Problem 3Difficulty: Mastery
Which statement correctly compares 7pi/10 radians and 130 degrees?
A7pi/10 radians is larger by pi/45 radians.
B130 degrees is larger by pi/45 radians.
CThe two angles are equal.
D130 degrees is larger by pi/10 radians.
Solution & Explanation:7pi/10 radians equals 126 degrees. The difference is 4 degrees, and 4 degrees equals 4pi/180 = pi/45 radians.
