Answer:
The radius of the circle is 4 units
The center of the circle is at (0, 10)
Step-by-step explanation:
The standard equation of a circle is
(x - a)² + (y - b)² = r²
where
(a, b) is the center of the circle
r = radius
For the equation x² + (y-10)² = 16.
we can rewrite as (x - 0)² + (y - 10)² = 4²
Hence radius r = 4
Center is at (0, 10)
