Discover What’s the True Area Hidden Beneath the Path?
A circular garden with a radius of 10 meters gains a 2-meter-wide path around it—what’s the space the trail covers? Curious homeowners, urban planners, and gardeners alike are exploring this question amid growing interest in efficient outdoor space design. What seems like a simple math problem reveals real-world insights into circular dimensions, landscaping strategy, and sustainable land use. This guide breaks down the calculation clearly, connecting geometry to practical application—so you understand exactly how pathways shape outdoor areas in the U.S.

Why This Circular Design Is Rising in Discussion
Across the U.S., compact, circular gardens with surrounding paths are becoming popular in suburban planning and eco-conscious landscaping. The 10-meter radius garden, surrounded by a 2-meter-wide loop, exemplifies a balanced blend of functionality and flow—ideal for maximizing usable ground while protecting green space. As urban dwellers seek smarter, greener designs, such layouts reflect a broader trend toward integrating nature into tighter living environments without sacrificing livability. The math behind these paths ties directly into real-life space optimization challenges.

How to Calculate the Area of the Path—Step by Step

Understanding the Context

To find the area of the path, imagine calculating two concentric circles: the inner garden and the outer ring that includes the path. The garden itself is a circle with a 10-meter radius. The path extends 2 meters beyond this edge, making the outer radius 12 meters total (10 + 2). The area of the path is the difference between these two circles.

The formula for a circle’s area is π × r². For the outer circle, the area is π × (12)² = 144π square meters. The garden’s area is π × (10)² = 100π square meters. Subtracting the garden from the full outer circle reveals the path’s area: 144π – 100π = 44π square meters. This translates to approximately 138.23 square meters using π ≈ 3.1416—though keeping it in terms of π maintains accuracy for professional and educational purposes.
