Step-by-step explanation:

You want the equation of a circle with center 3 units east of the origin, and radius 5 units.

Circle

The equation of a circle with center (h, k) and radius r is ...

  (x -h)² +(y -k)² = r²

The equation of a circle with center (3, 0) and radius 5 is ...

  (x -3)² +y² = 25 . . . . . . equation for edge of delivery area
