2pi radians
pi radians
pi/2 radians
3 pi/2 radians

Answer 1

[C]
`(\pi )/(2)\;radians`

Explanation:

The ray in the terminal position, after the rotation is call the "terminal side of the angle."

Note that quadrant of the unit circle of any given angle the radians would be in:

Quad I → 0 < θ < pi/2

Quad II → pi/2 < θ < pi

Quad III → pi < θ < 3pi/2

Quad IV → 3pi/2 < θ < 2pi

Hence, Answer is [C] pi/2 radians
