Answer:

x² - 22x + y² + 18y + 58 = 0

Explanation:

Using the equation of a circle :

(x - h)² + (y - k)² = r²

Solving :

Substitute 11, -9, 12 in place of h, k and r respectively.

  • (x - 11)² + (y + 9)² = (12)²
  • x² - 22x + 121 + y² + 18y + 81 = 144
  • x² - 22x + y² + 18y + 202 = 144
  • x² - 22x + y² + 18y + 58 = 0
