**An engineer is designing a circular track with a diameter of 200 meters. If the track is to have a uniform width of 10 meters, what is the area of the track itself?** Urban planners and architects are increasingly focused on creating high-performance outdoor spaces that balance functionality and sustainability. One growing trend involves designing running or cycling tracks that expand movement zones safely beyond the inner boundary—without rebuilding the full venue. A common scenario involves an existing circular track, currently 200 meters in diameter, with a uniform 10-meter-wide track ring added around it. This extension enhances usability while prioritizing safe, standardized distances—ideal for community sports, wellness trends, and public recreation. But how much surface area does this addition actually cover? Understanding the math behind track design reveals more than just numbers; it underscores thoughtful urban planning and efficient land use. An engineer is designing a circular track with a diameter of 200 meters. If the track is to have a uniform width of 10 meters, what is the area of the track itself? This project begins with a precise geometric foundation: the inner circle has a 200-meter diameter, meaning a radius of 100 meters. The outer boundary extends the circle outward by 10 meters, creating a larger circle with a radius of 110 meters. The area of the track itself is found by calculating the difference between the area of the outer circle and the inner circle—measuring how much open yet defined space surrounds the central running lane. **Calculating the Track Area: A Strategic Approach**
