The equation of a circle is x2 + (y-10)2=16. The radius of the circle is units. The center of the circle is at .

Answers:

Center = (0, 10)

Radius = 4

Work Shown:

Rewrite the equation into

(x - 0)^2 + (y - 10)^2 = 4^2

Then note how it is in the form

(x - h)^2 + (y - k)^2 = r^2

We see that the center is (h,k) = (0,10) and the radius is r = 4.
