What is the center and radius of the circle with the equation x2 + y2 + 8x – 12y + 36 = 0 ?. Center: (5, 6); Radius = 4. Center: (–4, 6); Radius = 5. Center: (5, 6); Radius = 5. Center: (–4, 6); Radius = 4.

Verified Answer :

The best and most correct answer among the choices provided by your question is the fourth choice which is "Center: (–4, 6); Radius = 4."

(x² + 8x) + (y² - 12y) = - 36 

(x² + 8x + 16) + (y² - 12y + 36) = - 36 + 16 + 16 

(x + 4)² + (y - 6)² = 16 

C (- 4 , 6 ) , r = 4

I hope my answer has come to your help. Thank you for posting your question here in Brainly.
