Degrees to radians conversion formula:
α in radians = α in degrees × π/180, OR
α rad = α° × π/180
Plugging the angle value, in degrees, in the previous formula, we get:
α rad = π × 175/180 =
π × 175÷5/180÷5 =
35π/36 radian, when reduced to lowest terms.
Note: 35π/36 rad can be expressed as a decimal (not a fraction) as 0.97222222222222π rad = 3.0543261909901 radian.
A: 175° = 35π/36 radian
