Radius is 3. Here is how: So you need to get two "square expressions". So there are y^2 but no y. So we have y^2. Then we have x^2 + 4x + (something). A perfect square is (x + 2)^2 = x^2 + 4x + 4. So we need to add 4 to both sides and we have x^2 + 4x + 4 + y^2 = 9. Or (x + 2)^2 + y^2 = 3^2. The radius is 3.
