What is the center of the circle (x + 2) 2 + (y - 5) 2 = 2.25?

This equation of the circle is in a center-radius form which is more generally written as,

(x - h) ² + (y - k) ² = r²

From the equation, the center of the circle is (h, k) and r is the radius. From the given equation above, the center of the circle is (-2,5).
