Write the equation of a circle that has a center at (5,-7) and a radius of 8

(x - 5)^2 + (y + 7)^2 = 64.

Step-by-step explanation:

The general form of the equation of a circle is

(x - a)^2 + (y - b)^2 = r^2    where (a, b) is the center and r = the radius.

So the given circle is

(x - 5)^2 + (y + 7)^2 = 8^2.

answer: 12

step-by-step explanation:

because yes
