Question

The equation of a circle is ​ (x−11)2+(y−9)2=225 ​ .



What is the center of the circle?

Answer 1

Answer:

(11,9)

Step-by-step explanation:

If a circle is given by its equation $(x-a)^2+(y-b)^2=r^2,$ then coordinates of the center are $(a,b)$ and radius is r.

In your case, for the circle with equation $(x-11)^2+(y-9)^2=225,$ you can state that coordinates of the center are (11,9) and radius is 15.

Answer 2

Answer:

The center of the circle is (11,9)
