Sequential evaluation with parameter substitution and unit tracking

Step & ParameterExpression & SubstitutionResult
1Tank radius
r = D / 2
= 2 / 2
= 1 m
2Circular cross-sectional area
A = πr²
= π × 1²
= 3.141593 m²
3Cylindrical-shell liquid volume
V_shell = A · h
= 3.141593 × 1.5
= 4.712389 m³
4Total liquid volume
V = V_bottom + V_shell + V_top
= 0 + 4.712389 + 0
= 4.712389 m³
5Liquid mass
m = ρ · V
= 1,000 × 4.712389
= 4,712.389 kg
