13pi/12=________ degrees: Round to the nearest hundredth.
Memorize the relationship:
π radians = 180°
from that you can solve for each unit :
1 radian = (180/π) ° <-------> 1 ° = (π/80) radians
so which ever is given, proceed from there
(13π/12) rad = (180/π)(13π/12) ° = 195°
(after a while, you get a "feel" for these values,
e.g. I think : π/12 <---> 15° , so 13 of those is 195° )
