Find the equation of the circle with centre (0, 2) and radius 2
Solution:
The equation of a circle with centre (h, k)
and radius r is given as
(x - h)2 + (y - k)2 = r2
It is given that centre (h, k) = (0, 2) and radius (r) = 2
Therefore,
the equation of the circle is
(x - 0)2 + (y - 2)2 = 22
x2 + y2 - 4y + 4 = 4
x2 + y2 - 4y = 0
