Answer 1

(x -4) + (y +3)² = 81

Explanation:

Equation of circle:

Center of the circle is the fourth quadrant. So, x will be positive and y will be negative.

S0, center is (4 , -3) and r = 9

Equation of circle:

`\boxed{\bf (x - h)^2 + (y -k)^2 =r^2}`

(h,k) is the center and r is the radius.

(x - 4)² + (y - [-3] )²= 9²

(x -4) + (y + 3 )² = 81
