Calculate the area of a circle of diameter 1.05m and express the result to an appropriate number of significant figures.
Take `pi =3.14`.

Explanation

To calculate the area of a circle with a given diameter and express the result to an appropriate number of significant figures, follow these steps:

### Step 1: Identify the diameter and the value of π
- Given diameter \( D = 1.05 \, \text{m} \)
- Given \( \pi = 3.14 \)

### Step 2: Use the formula for the area of a circle
The formula for the area \( A \) of a circle is given by:
