Answer:
center: (1/2, 6)
radius: √5
Step-by-step explanation:
The standard form equation for a circle of radius r and center (h, k) is ...
(x -h)^2 +(y -k)^2 = r^2
When we compare this to the given equation:
(x -1/2)^2 +(y -6)^2 = 5
we see that h=1/2, k=6, and r^2=5.
The center is (h, k) = (1/2, 6); the radius is √5.
