An arc on a circle measures 85°. the measure of the central angle, in radians, is within which range? 0 to radians to π radians π to radians to π radians

0 to π/2 radians.

A is the correct option.

Step-by-step explanation:

An arc on a circle measures 85°.

We know that central angle of a circle and the measure of the arc of the circle is equal.

Hence, the central angle should be also  85°

1 degree = 0.0174533 radians

85°= 1.48353 radians

85°= 1.48353 radians lies in the first quadrant. And in the first quadrant the range of the angle is 0 to π/2 radians.

Hence,  the range is 0 to π/2 radians.

A is the correct option.
