Answer 1

1.39626

Explanation:

80° × π/180 = 1.396rad

Answer 2

4π/9, 0.44444π, or 1.3962634 radians

Explanation:

To convert from degrees, to radians, multiply the the degrees times pi over 180 degrees

`\textdegree *(\pi )/(180\textdegree)`

We want to convert 80 degrees to radians.

`80 \textdegree *(\pi)/(180 \textdegree)`

The degrees signs cancel.

`80 *(\pi)/(180)`

`\frac {80}{1} *(\pi)/(180)`

Move 80 to the numerator.

`(80 \pi)/(180)`

Simplify 80/180. Both the numerator and denominator can be divided by 20.

`((80/20) \pi)/(180/20)`

`(4 \pi)/(9) \approx 0.444444\pi \approx 1.3962634`

80 degrees is equal to 4π/9 radians, 0.44444π radians, or 1.3962634 radians.
