Using Inches in the Sphere Volume Formula
In the United States and specialized aerospace industries, dimensions are frequently specified in inches. When radius is measured in inches, the resulting volume is in cubic inches (in³ or cu in).
Worked Example
Calculate the volume of a bowling ball with diameter d = 8.5 inches:
1. Radius: r = 8.5 / 2 = 4.25 in
2. Cube radius: 4.25³ = 76.7656 in³
3. Volume: V = 4/3 × 3.14159 × 76.7656 ≈ 321.39 cubic inches.
