Answer:
centre = (- 3, - 8), radius = [tex]\sqrt{6}[/tex]
Step-by-step explanation:
The equation of a circle in standard form is
(x - h)² + (y - k)² = r²
where (h, k) are the coordinates of the centre and r is the radius
(x + 3)² + (y + 8)² = 6 ← is in standard form
with centre = (- 3, - 8) and r = [tex]\sqrt{6}[/tex]
