Ok i need to find the center and the radius of each circle.
I know the equation is (x-a)^2 + (y-b)^2=r^2 with a and b representing the center of the circle and r is the radius.
ok one question is (x+7)^2 + (y-8)^2 = 36/25
i got the center is (7, -8) and the radius is 6/5 is that right?
The other question im completely confused on its:
(x+a)^2 + (y-b)^2= c^2
Please help if possible!!
Thanks
