For the circle below, what statements are true (circle will be attached after)
1. If the measure of a (theta) is 1 radian, then the arc length is 2r.
2. If the measure of the (theta) is 60 degrees, then the arc length is r.
3. The ratio of arc length to r is always equal to pi.
4. If the ratio of an arc length to r is 1, then the measure of theta is 1 radian.

***[isuru]*** · Answer

when  the angle is measured in radian 
    $$S = r \theta$$
where
 S = arc length
r = radius
theta = the angle
