Equation of a circle   (x - 5)² + (y + 18)² = 36

The equation of the circle in standard form is (x - h)² + (y - k)² = r²,

where the coordinates of the center are (h, k).

Then just get the h, k values and change the signs.

h = -(-5) = 5

k = -(18) = -18

the x-coordinate = 5

the y-coordinate = -18
