Question

An arc on a circle measures 125°. The measure of the central angle, in radians, is within which range?

Answer 1

π/2 to π radians

Answer 2

`[0,2\pi]`

Explanation:

Central angles are subtended by an arc between those two points.

The arc length is the central angle of a circle of radius one (measured in radians).

The central angle is also known as the arc's angular distance.

Here given that 125 degrees is the measure of an arc on a circle

The central angle will vary between 0 and 360 degrees

In radians this range can be specified as

`[0,2\pi]`
