forget textbooks telling you "formulae" like this.

Learn the definition!

360 degrees is 2%2Api radians. That is all you need to know!

so, 360 IS 2%2Api
then 1 IS %282%2Api%29%2F360
then 12 MUST BE 12%2A%28%282%2Api%29%2F360%29
--> %2824%2Api%29%2F360
--> pi%2F15 radians
--> leave like this or work out on calculator and round it.
