Question

In which quadrant does the angle with measure 2.1 radians lie?

let π =3.14

a quadrant I

b quadrant ii

c quadrant ii

d quadrant iv

Answer 1

the answer to the question is b because half of pi is about 1.57 so 2.1 radians would fall into the second quadrant

Answer 2

Quadrant II.

Explanation:

Keep in mind that one radian is approx. 57 degrees.

Thus, 2 rads would be approx. 114 degrees.

That'd be in Quadrant II.

2.1 rads would be approx. 120 degrees, which is still in Quadrant II.
