(x + 9)^2 + (y + 6)^2 = 225 circle center | (-9, -6) radius | 15 diameter | 30 area | 225 π≈706.858 perimeter | 30 π≈94.2478 centroid | (-9, -6) curvature | 1/15≈0.0666667

(x + 9)² + (y + 6)² = 225 (x + 9)² + (y + 6)² = 15² The typical equation of a circle is: (x - xo)² + (y - yo)² = R² → where: xo: abscissa of center → (- 9) in your case yo: ordinate of center → (- 6) in your case R: radius of circle → 15 in your case

Let (h,k) = the center point of the circle Let h represent x and k represent y x + 9 = 0 x = -9 y + 6 = 0 y = -6 The center point is (-9,-6).

(x-(-9))^2 +(y-(-6))^2 = 15^2 (x-h)^2 +(y-k)^2 = r^2 h=-9 k=-6 center (-9,-6)

(x - a)^2 + (x - b)^2 = r^2 centre: (a, b) radius: r (x + 9)^2 + (y + 6)^2 = 225 (x - (-9))^2 + (y - (-6))^2 = 225 centre: (-9, -6)
