Calcolatore di Volume e Superficie del Cono — Formula

Cone Formulas

Volume

V = (1/3) × pi × r² × h

Slant Height

l = sqrt(r² + h²)

Surface Area

  • Lateral area = pi × r × l
  • Total area = pi × r × l + pi × r² = pi × r × (l + r)

    • Esempio Risolto

    Cone with radius 4 and height 9.

    1. Slant = √(16+81) = √97 ≈ 9.8489
    2. Volume = (1/3)×pi×16×9 = 48pi ≈ 150.7964
    3. Lateral SA = pi×4×9.8489 ≈ 123.7168
    4. Total SA = 123.7168 + pi×16 ≈ 173.9460
