Question

Find an equation of a circle that satisfies the given conditions.

Center (–2, –8), radius 10

Answer 1

The equation of a circle with center (h, k) and radius r is given by:

(x - h)^2 + (y - k)^2 = r^2

In this case, the center is (-2, -8) and the radius is 10, so the equation is:

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

(x + 2)^2 + (y + 8)^2 = 100
