The equation for a circle is:
(x - h)^2 + (y - k)^2 = r^2
h = the x value of the center
k = the y value of the center
r = length of radius
In this case the center is (2, 1) and the radius is 2 units, meaning:
h = 2
k = 1
r = 2
The equation for this circle is:
(x - 2)^2 + (y - 1) = 4
This matches the equation given in the question so the answer is True!
Hope this helped!
