Method
Formula, when it applies, and when it does not
Resolve a right circular cylinder’s volume, end area, and lateral surface from its displayed diameter and length.
V = π(D/2)²L; Aend = π(D/2)²; Alateral = πDL
When
- Right circular cylinder
- Uniform diameter
- Nominal geometry only
Don’t
- This is nominal closed-cylinder geometry. Wall thickness, end shape, internal fittings, deformation, and manufacturing tolerances are outside the model.
