3 Points On A Circle

To start with, this is my first post, I'm new here, and I have no idea if this is in the correct place. I'm 17, and a sophmore in college (community college of denver). Just a simple question that has been racking my brain because I seem to have forgotten how to do this.

You have a circle and 3 points lie on the circumfrence. If you draw a triangle between the 3 points the lengths of the legs are 5.25", 4.625", and 4.3125" respectively. What is the diameter of the circle??

I know that I should know this I just don't remember it. Any help is appreciated. Thank you in advance.
