how to convert 22.5 radians into pi form?

Question

tkhunny · Answer

Ummm...  a "radian" isn't really a thing.  It's just a number.

22.5/pi = 7.16197243913529

Thus, 22.5 = 7.162pi (give or take)

The options given are 13pi/8, pi/8, 9pi/8 or 5pi/8. The original question was find the supplement of the radian measure 7pi/8. Express answer in terms of pi.

It is SO much easier to ask the right question.

Supplemental Angles add to $\pi$.  The supplement to 7$\pi$/8 is $\pi$/8.  There is no point to converting to angle measure.  What you should have asked, after pointlessly converting to degrees, is what is the Radian equivalent to 22.5º.  That would be $\pi$/8.
