Circle Radius

Hey guys, can someone help me out with this question and explain to answer to me?

A triangle is inscribed in a circle such that one side of the triangle is the diameter. If one of the acute angles measures 60 (or pi/3), and the side opposite that angle has a length of 12, find the circle's radius.

Thanks for the help!

We can help - we only help after you have shown your work - or ask a specific question (not a statement like "Don't know any of these")

Please share your work with us indicating exactly where you are stuck - so that we may know where to begin to help you.
 
Well I actually have a lot of work done in my sketch of my circle on paper, but I don't know how I would show that on this forum. Sorry for the issue.
 
You can explain your reasoning, strategy, approach, anything that shows some effort, really. :cool:

For example, you did something, but why did you stop?

PS: Do you know? If you pick any point A on a semicircle such that connecting it to each end of the diameter forms a triangle, then the angle at vertex A is always 90 degrees.
