Question 887334
Use the given arc length and radius to find the angle θ (in radians).
The arc length is 49 and the radian [sic?] is 70. I got .7, however my answer was incorrect.
-----------------
arc length = angle*radius
49 = angle*70
angle = 49/70 = 0.7 radians

It doesn't happen often, but sometimes the book (or site) is wrong.
