The center is (-10,10) Â and the radius is 4sqrt(3)
Step-by-step explanation:
(x + 10)^2 + (y - 10)^2 = 48
We can write the equation of a circle as
(x -h)^2 + (y - k)^2 = r^2 Â where (h,k) is the center and r is the radius
(x- Â -10)^2 + (y - 10)^2 = (sqrt(16*3) )^2
(x- Â -10)^2 + (y - 10)^2 = (4sqrt(3)) ^2
The center is (-10,10) Â and the radius is 4sqrt(3)
