Question
Encontre a equação da circunferência, sabendo-se que A(-4, 6) e B(6, 2) são extremidades de um diâmetro.
Answer
\((x-1)^2+(y-4)^2 = 29\)
\((x+1)^2+(y+4)^2 = 29\)
\((x-1)^2+(y-2)^2 = \sqrt{29}\)
\((x-2)^2+(y-2)^2 = \sqrt{29}\)
Question 2
Question
Ache a medida do raio e as coordenadas do centro da circunferência \(4x^2+4y^2-24x+4y +1=0\).
Answer
r=3 e C=(3, -\frac{1}{2})
r=9 e C=(3, -\frac{1}{2})
r=3 e C=(1, -\frac{1}{4})
r=9 e C=(1, -\frac{1}{4})
