If you draw this out it looks like this|dw:1402325038411:dw|Do you know what the radius of the circle is when you look at it like that?

The diameter can be found by splitting the square into 2 right triangles with legs of 3.  Find the hypotenuse and you know the diameter of the circle.  So you could use the formula C = pi*d to find the circumference.  Do you know what the diameter is?  Can you find it?
