My standardform equation is (x+3)^2+(y+2)^2=4. Do I find the radius by doing the square root of four? I just wanted to check on this. Based on the example in my book, it seemed like this is the way to do this, but I wanted to make sure, because they didn't come right out and say that. Thanks for your help!!

yes, in standard form, the radius is the square root of the right hand side.
