    A square park is modeled by the region ​0≤x≤8​ and ​0≤y≤8​ (all distances in meters).

    There are three refreshment kiosks.

    • Kiosk ​A​ is at the point ​(2,6).

    • Kiosk ​B​ is at the point ​(2,b).

    • Kiosk ​C​ is at the point ​(6,6).

    A Voronoi diagram of the park's kiosks is shown below:
