Give the coordinates of the circles center and its radius
(x-7)^2 + (y+4)^2 = 16
\(y= \sqrt{16- \left(x-7\right) ^{2}} -4\)
coordinates of the circles: 7 / - 4
r = 4
Greeting asinus :- ) 
!
+33616 Generally, the equation of a circle can be written as:
(x - a)^2 + (x - b)^2 = r^2
where the centre coordinates are (a, b) and the radius is r.
Here a = 7, b = -4 and r = 4
