Find the centre and radius of each of the following circles : (i) ` (x - 3)^(2) + (y- 1) ^(2) = 9` (ii) ` (x - (1)/(2) ) ^(2) + ( y + (1)/(3) ) ^(2) =
Find the centre and radius of each of the following circles :
(i) ` (x - 3)^(2) + (y- 1) ^(2) = 9`
(ii) ` (x - (1)/(2) ) ^(2) + ( y + (1)/(3) ) ^(2) = (1)/(16)`
(iii) ` (x + 5) ^(2) + ( y- 3 ) ^(2) = 20`
(iv)` x ^(2) + (y- 1 ) ^(2) = 2 `

Correct Answer - (i) Centre ` (3, 1 )`, radius = 3
(ii) Centre ` ((1)/(2), (-1)/(3))`, radius `= (1)/(4)`
(iii) Centre ` (-5, 3 )` , radius = ` 2sqr5`
(iv) Centre `(0, 1 )`, radius `= sqrt 2`
