Formula Nature & Mechanics
Linear Scaling: Circumference scales directly in 1:1 proportion with radius.
Common Mistakes & Traps
- Confusing radius (r) with diameter (d = 2r) — always halve the diameter if given.
- Forgetting to square the units (e.g. output is in m² or cm², not linear m).
- Using a rounded value of π too early in multi-step calculations.
Dimensional Analysis & Units
[Length] → Result in linear units (e.g., m, cm)

Worked Example: Volume of Sphere
Given:
- r = 3
- V = (4/3)πr³
- V = (4/3)π(3)³
- V = (4/3)π(27)
- V = 36π
- V = 113.09733552923254 cubic units
Answer: 113.09733552923254
