Question 193914: please Find the radius and center of each circle.

12. (x - 2)^2 + (y - 3)^2 = 16
13. x^2 + (y + 4)^2 = 8
14. (x + 1)^2 + (y - 2)^2 = 12
15. (x - 6)^2 + y^2 = 25

The equation of a circle with center at (h, k) is:



So, for your first problem, the center is at (2, 3) and the radius is

Do the rest of them the same way.

Hint:

Hint: if is not a perfect square, leave the answer in radical form.
