Maharashtra Board Solutions for Chapter: Circle, Exercise 2: EXERCISE 6.2

Find the centre and radius of the circle ${\mathrm{x}}^2+{\mathrm{y}}^2-2\mathrm{x} +4\mathrm{y}-4=0$

Find the centre and radius of the following 

${\mathrm{x}}^2+{\mathrm{y}}^2-6\mathrm{x}-8\mathrm{y}-24=0$

Find the centre and radius of the following

$4x^2+4y^{2 }-24x-8y-24=0$

Show that the equation $3{\mathrm{x}}^2+3{\mathrm{y}}^{2 }+12\mathrm{x}+18\mathrm{y}-11=0$ represents a circle.

 Find the equation of the circle passing through the points $(5, 7), (6, 6)$ and $(2, -2)$. 

Show that the points $(3,-2),(1,0),(-1,-2)$ and $(1, -4)$ are concyclic.
