Question

i'm having trouble converting radians to degrees:
7π/11
ty in adv

Answer 1

Remember 2pi radians = 360 degrees... So I like writing these like this... \[(7\pi/11)/(2\pi) = x/360\]
Which looks better when you write it out on paper. But then cross multiply and divide...
\[(7\pi/11)*360= x*2\pi\]
then just divide both by 2pi to get x.

Answer 2

pi radians = 180 degrees
so 7pi/11 = 7pi/11 / (180/ pi) degrees
