The sides of a square are `x=6,\ x=9,\ y=3\ a n d\ y=6.` Find the equation of a circle drawn on the diagonal of the square as its diameter.

Explanation

Given: sides of a squares are` x=6, x=9, y=3 and y=6`


Assume A, B, C, D be the vertices of the square.


By solving the lines, the coordinates as:


`A=(6,3)`


`B=(9,3) `


`C=(9,6)`


`D=(6,6)`


The equation of the circle with diagonal AC is
