Question

I was thinking the answer was 4 but I am not sure at all

Answer 1

The formula for the equation of a circle is (x – h)² + (y – k)² = r², where (h, k) represents the coordinates of the center of the circle, and r represents the radius of the circle.

Therefore, for the equation:

`\begin{gathered} (x+7)^2+(y+7)^2=16 \\ r^2=16 \\ r=\sqrt[]{16} \\ r=4 \end{gathered}`

Answer:

4
