Find the equation of the circle with center at `(3,-1)` and which cuts off an intercept of length 6 from the line `2x-5y+18=0`

Text Solution

Verified by Experts

The correct Answer is:
`(x-3)^(2)+(y+1)^(2)=38`
Let the circle be as shown below.
`CM=(|2(3)-(5(-1)+18)|)/(sqrt(2^(2)+(-5)^(2)))=sqrt(29)`

`:. AC^(2)=AM^(2)+CM^(2)=9+29=38`
`:. ` Radius `=sqrt(38)`
