The Radius 3 Geometric Coincidence
For radius = 3$, an intriguing numerical coincidence occurs where the numerical magnitude of volume equals the numerical magnitude of surface area:
Volume: V = ⁴⁄₃ × π × 3³ = ⁴⁄₃ × π × 27 = 36π ≈ 113.10 cm³
Surface Area: A = 4 × π × 3² = 4 × π × 9 = 36π ≈ 113.10 cm²
Surface Area: A = 4 × π × 3² = 4 × π × 9 = 36π ≈ 113.10 cm²
While the numbers match ($36\pi$), their physical units are fundamentally different: capacity in cubic units versus area in square units.
