Radian question. Answer asap please!!!

Answer 1

Answer:

Ф = s/r

Step-by-step explanation:

The arc length formula is s = rФ, where r is the radius and Ф is the central angle.  We want to find a formula for the angle Ф in terms of s and r.  To do this, start with s = rФ and divide both sides by r:

s     rФ

-- = ----

r       r

Then Ф = s/r
