Find the radius of the circle (x-5)(x-1)...

Find the radius of the circle `(x-5)(x-1)+(y-7)(y-4)=0` .

Text Solution

Verified by Experts

The correct Answer is:
`5//2`
The extremities of diameter are (5,7) and (1,4). The radius is half of the distance between them, i.e.,
`(1)/(2) sqrt((5-1)^(2)+(7-4)^(2))=(5)/(2)`
