Find the centre a

The general form of the equation of a circle is:

(x - h)² + (y - k)² = r²

Where, (h, k) is the centre of the circle.

r is the radius of the circle.

Comparing the given equation of circle with general form we get:

h = 0 , k = 1, r² = 2

⇒ centre = (0, 1) and radius = √2units.

Ans: centre = (0, 1) and radius = √2units.
