Convert by multiplying the expression by 180/pi

Explanation:

(5pi)/12 xx (180/pi)

We can simplify the fractions before multiplying: the pi's eliminate themselves and the 180 is divided by 12, which gives 15.

= 15 xx 5

= 75 degrees

The rule is the opposite when converting from degrees to radians: you multiply by pi/180.

Practice exercises:

  1. Convert to degrees. Round to 2 decimals if necessary.

a) (5pi)/4 radians

b) (2pi)/7 radians
