Question

Convert 72degrees into radians

Answer 1

72° = 1.25 radians

Explanation:

As we know that,

`1 degree = (\pi)/(180) radians`

Thus,
`72^(\circ) = 72*(\pi)/(180)radians`

⇒
`72^(\circ) =(2\pi)/(5)radians`

⇒ 72° = 1.25 radians {∵ Using π = 22÷ 7 or 3.14}

Both degrees and radians are used to measure the angle. They are units of angle.
