been found to be 335 seconds. In a study of the effectiveness of hypnotic therapy, 30 males of the appropriate age are given the treatment and then their latency to fall asleep is measured.

Find the length of the arc (AB) Leave your answer in terms of Pi
butalik [34]
The formula is L = 2 pi r * (angle measure / 360). We have everything we need to solve this, the angle is 90 and the radius is 12: L = 2 pi (12) (90/360). Do the work inside the parenthesis first to get : L = 2 pi (12)(.25). Solving for L: L = 6pi

If we plug in zero for x , then we would be dividing by zero which is impossible. Thus the domain is all real numbers except for zero.
