A racetrack is in the form of a ring whose inner and outer circumferences are `437` m and `503` m respectively. Find the width of the track and also its area.

Explanation

To solve the problem of finding the width and area of a racetrack in the form of a ring with given inner and outer circumferences, we can follow these steps:

### Step 1: Identify the given values
- Inner circumference (C1) = 437 m
- Outer circumference (C2) = 503 m

### Step 2: Use the formula for circumference to find the radii
The formula for the circumference of a circle is given by:
