Answer 2

(0, 9)

Explanation:

The circle defined by the equation ...

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

has its center at (h, k).

We think your circle's equation is ...

x^2 + ( y − 9 )^2 = 81

so it would have its center where h = 0 and k = 9.

The center is (0, 9).

Comment on the question

Sometimes, copying and pasting seems to cause things to be repeated 3 times, usually in different formats. It would be nice to have one clean copy of the equation, so we can easily tell what it is supposed to be. Editing may be required, to make sure all necessary math symbols are included.
