AIEEE 2004 | Circle Question 151 | Mathematics

If the two circles $${(x - 1)^2}\, + \,{(y - 3)^2} = \,{r^2}$$ and $$\,{x^2}\, + \,{y^2} - \,8x\, + \,2y\, + \,\,8\,\, = 0$$ intersect in two distinct point, then :

$$r > 2$$

$$2 < r < 8$$

$$r < 2$$

$$r = 2.$$

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 :

$${x^2}\, + \,{y^2} - \,2x\, + \,2y\,\, = \,62$$

$${x^2}\, + \,{y^2} + \,2x\, - \,2y\,\, = \,62$$

$${x^2}\, + \,{y^2} + \,2x\, - \,2y\,\, = \,47$$

$${x^2}\, + \,{y^2} - \,2x\, + \,2y\,\, = \,47$$
