Find the centre and radius of the circle...

Find the centre and radius of the circles`(x+5)^2+(y-3)^2=36`

Text Solution

Verified by Experts

`(x+5)^(2)+(y-3)^(2)=36`
Comparing with `(x+5)^(2)+(y-k)^(2)=r^(2)`
`h=-5,k=3,r^(2)=36`
`rArr" "h=-5,k=3,r=6`
`:.` Centre of circle `-=(h,k)-=(-5,3)`
and radius = 6 units
