An arc on a circle measures 85°. the measure of the central angle, in radians, is within which range?

85 degrees in radians is 1.48353 so if there are answer choices around this then that would be the answer.

The central angle is equal to 85°. Convert 85° into Radian:
Apply the conversion formula:
Radian/π = Degree/180°

Radian/π = 85°/180°

Radian = π(85/180) = (17π)/36 [after simplification]
So 85° ≈(17π)/36 = 1.48353
