Findthe equationof the circlepassingthrough the points(i)(0,0), (5, 0) and(3, 3)(ii)(1, 2 ), ( 3, -4) and( 5, - 6)(iii)( 20, 3) , (19, 8) and (2, -9)Also, find the centreand radiusin each case.

Answer»


Answer :(i) `x ^(2)+ y ^(2)- 5x- y= 0 `, CENTRE` ((5)/(2), (1)/(2))` and radius=` (sqrt( 26))/( 2)`
(ii) ` x ^(2) + y ^(2) - 22x-4y+25 = 0`, centre` (11,2) ` and radius= 10
(III)` x ^(2)+ y ^(2) - 14 x- 6y - 111 = 0 `, centre ` (7, 3)`and radius= 13
