write the equation of the circle centered at (3, -2) with radius 11.

Explanation:

Step1: Recall circle - equation formula

The standard form of a circle's equation is $(x - h)^2+(y - k)^2=r^2$, where $(h,k)$ is the center and $r$ is the radius.

Step2: Substitute values

Here, $h = 3$, $k=-2$, and $r = 11$. So we get $(x - 3)^2+(y+2)^2=121$.

Answer:

$(x - 3)^2+(y + 2)^2=121$
