Question
The lines 2x - 3y = 5 and 3x - 4y = 7 are diameters of a circle having area as 154 sq units. Then the equation of the circle is
Options
A.x2 + y2 + 2x - 2y = 62
B.x2 + y2 + 2x - 2y = 47
C.x2 + y2 - 2x + 2y = 47
D.x2 + y2 - 2x + 2y = 62
Solution
Intersection of diameter is the point (1, - 1)
πs2 = 154
⇒ s2 = 49
(x - 1)2 + (y + 1)2 = 49
Hence, (C) is the correct answer.
πs2 = 154
⇒ s2 = 49
(x - 1)2 + (y + 1)2 = 49
Hence, (C) is the correct answer.
