Answer:
center = (0, 2)
radius = √2
Explanation:
x² + (y + 2)² = 2
the general equation of the circle is,
(x - h)² + (y - k)² = r²
where (h, k) is the center of the circle and
r is the radius of the circle
given equation of the circle is,
x² + (y + 2)² = r²
(x - 0)² + (y - 2)² = 2
thus the center of the circle is, (0, 2)
radius, r² = 2
r = √2
