Talia Mueller · Answer 1

The eqation with center at (h, k) and having a radius of r is

(x-h) ² + (y-k) ²=r²

given

cetner is (2,-8) and radius is 11

(x-2) ² + (y - (-8)) ²=11²

(x-2) ² + (y+8) ²=121

B is answer

Which equation represents a circle with a center at (2, - 8) and a radius of 11?A. (x - 8) 2 + (y + 2) 2 = 11B. (x - 2) ² + (y + 8) ² = 121C. (x + 2) ² + (y - 8) ² = 11D. (x + 8) ² + (y - 2) ² = 121
