We do not do your work for you. Here is a source with a (relatively) simple formula for calculating r.

In the future, you can find the information you desire more quickly, if you use appropriate key words to do your own search. Also see http://hanlib.sou.edu/searchtools/.

I hope this helps. Thanks for asking.
I DID NOT ASK YOU TO DO MY HOMEWORK, I JUST WANTED THE FORMULA.....
