Question

Which of the following are in the correct order from least to greatest?



2pi, 7pi/6, 80°, pi/4, 38°


38°, 80°, pi/4, 7pi/6,2pi


38°, pi/4, 80°, 7pi/6, 2pi


2pi, 38°, 80°, pi/4, 7pi/6

Answer 1

(Writing 20 plus characterssssssssssss) the answer is c

Answer 2

Answer:

38°, pi/4, 80°, 7pi/6, 2pi

Explanation:

To convert radians to degrees, multiply by 180.

This means that pi/4 = 180/4 = 45°.

This also means that 7pi/6 = (7*180)/6 = 1260/6 = 210°.

2pi = 2*180 = 360°

This means from least to greatest, we have

38°, 45°=pi/4, 80°, 210°=7pi/6, 360°=2pi
