Answer:
Center = (0, -10)
Radius = 4 units
Step-by-step explanation:
[tex]x^2 + (y - 10)^2 = 16\\(x-0)^2 + (y - 10)^2 = 4^2\\Equating\: it \: with\: \\(x-h)^2 + (y - k)^2 = r^2\\We\: find:\\-h = 0\implies h = 0\\-k = -10\implies k = 10\\Center = (-h,\:-k) \\Center = (0,\:-10) \\r^2 = 4^2\implies r = 4\\Radius = 4\:units[/tex]
