Question

What is the formula for arc length?

Answer 1

If s=arc length, and
r=the radius of the arc in question,
and
theta=the central angle corresponding to the arc,

then s = r (theta), or \[s=r \theta\]

Answer 2

Note: the central angle MUST be expressed in radians (not in degrees).

Answer 3

alright. Thank you so much! Your a life saver!

Answer 4

My pleasure. Have fun calculating arc length! ;)

Answer 5

Lol thank you :)

Answer 6

Oh one more thing you said it was s= r.. how do you do the 0 with the line through it?
