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

i believe the correct answer is option 4.principalities were small territories that were run by russian rulers.

which statement correctly defines principalities in northern asia in the 1200s? principalities were small territories that were run by russian rulers.

hope i could ! : )
