Question

What is the equation of a circle with center (–4, 7) and radius 4?

Answer 1

[AI-generated answer — Bot GPT 3.5]

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

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

In this case, the center is (-4, 7) and the radius is 4. Plugging these values into the equation, we get:

(x - (-4))^2 + (y - 7)^2 = 4^2

(x + 4)^2 + (y - 7)^2 = 16

Therefore, the equation of the circle is (x + 4)^2 + (y - 7)^2 = 16.
