### Solution

#### Given

In this question, we are given

• The diameter of a circular skating rink is 60 meters.

#### To Find

We need to determine

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

#### 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.
