Question

Find the Centre of a circle passing through the points (6,-6) (3,-1) and (3,3)​

Answer 1

Answer:

i think the question must be (6,-6) (3,-7) (3,3)

Step-by-step explanation:

so here's an example

answered Dec 29, 2018 by Vikash Kumar (257k points) Let O(x,y) be the center of the circle passing through A(6, -6), B(3, -7) and C(3, 3) Substituting y = -2 in (1) Therefore, The centre of the circle is (3,-2)

Answer 2

Answer:

Let O(x,y) is the center of the circle and A(6.−6),B(3,−7) and C(3,3)are the points on the circumference of the circle.

∴OA=(x1−x2)2+(y1−y2)2

⇒OA=(x−6)2+(y+6)2

⇒OB=(x−3)2+(y+7)2

⇒OC=(x−3)3+(y−3)2

∵ Radii of the circle are equal 

∴OA=OB

⇒(x−6)2+(y+6)2=(x−3)2+(y+7)2

⇒x2+36−12x+y2+36+12y=x2+9−
