Write the equation of the circle with a center at ( - 2, - 8) and a radius of sqrt (10).

(x + 2) ^2 + (y + 8) ^2 = 10

Step-by-step explanation:

The general equation of a circle with center at (h, k) and radius r

is (x - h) ^2 + (y - k) ^2 = r^2. If the center is at (-2, - 8) and the radius is √10, then this equation becomes:

(x + 2) ^2 + (y + 8) ^2 = 10
