__To Find__

__To Find__

We need to determine

- The approximate value of the area of the rink, in square meters.

__Approach & Working__

__Approach & Working__

As the diameter of the rink is 60 meters, the radius of the rink = 30 meters.

- Therefore, the area of the rink = π (30)
^{2}= 900π - Assuming π = 3.1 (approximate), area = 900π = 900 * 3.1 = 2800 (approximate)

Hence, the correct answer is option D.
