How is Radian defined?
A) ⊖=s/r where ⊖ is a central angle and arc +s+ is equal to radius r
B) ⊖=s/r where ⊖ is an included angle and arc +s+ is equal to radius +r+
C) ⊖s/r where ⊖ is a central angle and arc +s+ is equal to radius +r+
D) ⊖=s/r where ⊖ is an included angle and arc +s+ is equal to radius +r+ 
----------------
The radian measure of a central angle of a circle is
the length of the angle's included arc divided by
the radius of the circle.
