Tianna Bentley · Answer 1

(x-2) ^2 + (y+8) ^2 = 121

Step-by-step explanation:

We can write the equation of a circle as

(x-h) ^2 + (y-k) ^2 = r^2

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

(x-2) ^2 + (y - - 8) ^2 = 11^2

(x-2) ^2 + (y+8) ^2 = 11^2

(x-2) ^2 + (y+8) ^2 = 121

Todd Calderon · Answer 2

(x - 2) ² + (y + 8) ² = 121

Step-by-step explanation:

(x - h) ² + (y - k) ² = r²

(x - 2) ² + (y - - 8) ² = 11²

(x - 2) ² + (y + 8) ² = 121
