(x+3)² + (y-4)² = 25penjelasan....
(X - Xpusat)² + (Y - Ypusat)² = jarijari²
sedangkan jari-jari = jarak antara pusat lingkaran (-3,4) dengan titik (yang melalui) pada lingkaran (0,0) =
r= √(0-(-3))² + (0-4)²
= 5

Kelas 11 MatematikaBab Persamaan Lingkaran
Titik asal = (0, 0)
(x - h)² + (y - k)² = r
(0 + 3)² + (0 - 4)² = r²
9 + 16 = r²
r² = 25
(x - h)² + (y - k)² = r²
(x + 3)² + (y - 4)² = 25
x² + 6x + 9 + y² - 8y + 16 - 25 = 0
x² + y² + 6x - 8y = 0
