Dada la ecuación de la circunferencia:
X² + Y² -2/3X +3/5Y +1/75 = 0
D = -2/3
E = -3/5
F = 1/75
Ecuaciones para determinar:
Coordenadas del centro de la circunferencia y el radio:
h = -D/2
k= -E/2
r = (√D²+E² -4F)/2
h = -(-2/3)/2 = 2/6 = 1/3
k = -(-3/5)/2 =3/10
r =[√(2/3)² + (3/5)² -4(1/75)]/2
r =[√(4/9 + 9/25 -4/75)]/2
r =[√(300 + 243 -36/675)]/2
r = 0,43
