What are the center and radius of the circle given by the equation? (x-3) ^2 + (y+4) ^2=4

A. (3, - 4); 2

B. (-3, 4); 2

C. (3, - 4); 4

D. (-3, 4); 4

General formula of the circle

(x-a) ² + (y - b) ² = r²,

where (a, b) - coordinates of the center, r - radius of the circle.

(x-3) ² + (y+4) ²=4

(x-3) ² + (y+4) ²=2²

So, the center is (3, - 4) and radius r = 2.

A. (3, - 4); 2
