cos R = .4/.633=.632, R=50.802

It has been a long time since I have used cos functions. I want to know how to find R given that cos R = .632. I am looking at an old HW problem and the answer for R is 50.802 (although I don't really know if it is correct).

I need to compute the length of a cycle = 360/R.
