What this tool does
Volume grows with the cube of the radius, so doubling a ball's radius makes it eight times heavier — the reason large spherical tanks and bearings get heavy so quickly. Surface area grows only with the square.
Formula
V = (4/3) × π × r³ , A = 4 × π × r²

Limitations
- Mixing units is the most common source of error. Convert every input to the units shown next to each field before calculating.
