The diameter of a sphere is 4.24 m . Calculate its surface area with due regard to significant figures.

Explanation

To calculate the surface area of a sphere given its diameter, we can follow these steps:

### Step 1: Identify the diameter and calculate the radius
The diameter of the sphere is given as 4.24 m. The radius (r) can be calculated using the formula:
\[ r = \frac{d}{2} \]
where \( d \) is the diameter.
