Question

What is the center of the circle represented by this equation? x2 + (y + 9)2 = 25

Answer 1

The point is (0,9) with a radius of 5 and a diameter of 10

Explanation:

Answer 2

Comparing the given equation to the standard form for the equation of a circle,
(x -h)² + (y -k)² = r²
we find that
h = 0
k = -9
r = 5

The circle is centered at (h, k) = (0, -9). It has radius 5.
