Question

What is the center of the circle with this equation is (x+2)²+(y-4)=41?

Answer 1

(h, k) is (-2, 4) and the radius is √41

Explanation:

Compare the given equation with the general equation, which is good for circles with center at (h, k) and radius r:

(x - h)^2 + (y - 4)^2 = 41

Here the comparison shows that (h, k) is (-2, 4) and that the radius is √41.
