Torus Formulas

Volume

V = 2 × pi² × R × r²

Surface Area

SA = 4 × pi² × R × r

Where:

  • R = major radius (distance from the center of the torus to the center of the tube)
  • r = minor radius (radius of the tube itself)

    • A torus is the 3D shape formed by revolving a circle around an axis in the same plane.

    Exemple Résolu

    Torus with major radius 5 and minor radius 2.

    1. Volume = 2 × pi² × 5 × 4 = 40pi² ≈ 394.7842
    2. Surface area = 4 × pi² × 5 × 2 = 40pi² ≈ 394.7842
