Question

Find the center and radius of the circle described by the equation x2 + y2 + 6x - 4y - 27 = 0.

Answer 1

Answer:

Step-by-step explanation:

hello :

x²+ y² + 6x - 4y - 27 = 0 means : (x²+6x+9)-9+(y²-4y+4)-4-27 =0

(x+3)²+(y-2)² = 40....standard form when the center is (-3 , 2) and radius √40
