Question

What is the formula for finding the length of an arc, using radians and degrees?

Answer 1

Assuming this is an arc of a circle use the ratio of arc degrees divided by 360

Explanation:

If you know the radius and the arc in degrees :

arc length = `x^o/360^o 2pir`

If you know the radius and the arc in radians :

arc length = `(radians)/(2pi) 2pir=(raidans)r`

hope that helped
