Programa para Volumen y Área Superficial de Frusto de Cono

Dada la altura inclinada, la altura y el radio de un tronco de cono, tenemos que calcular el volumen y el área de superficie del tronco de un cono.

Frusto de cono
En geometría, un tronco de cono es la porción de un sólido (normalmente un cono o una pirámide) que se encuentra entre uno o dos planos paralelos que lo cortan.
Si cortamos un cono circular recto por un plano paralelo a su base, la parte del sólido entre este plano y la base se conoce como tronco de cono.

A continuación se muestra un cono circular recto.


The right circular cone after being cut by a plane parallel to its base results in a frustum as follows:


which has a circular base at bottom of radius R
circular upper portion with radius r
height h
and slant height l

  • Volumen del tronco de cono:
Volume (V) = 1/3 * pi * h(r2 + R2 + r*R)

where
r = radius of smaller circle
R = radius of bigger circle (or radius of base of the cone)
h = height of the frustum
  • Área de superficie curva del tronco de cono:
  • Curved Surface Area (CSA) = pi * l(R + r)
    
    where
    r = radius of smaller circle
    R = radius of bigger circle
    l = slant height of the frustum
    
  • Área de superficie total del tronco de cono:
  • Total Surface Area (TSA) = pi * l(R + r) + pi(R2 + r2)
    
    where
    r = radius of smaller circle
    R = radius of bigger circle
    l = slant height of frustum
    

    Ejemplos:

    Input : Radius of smaller circle = 3
            Radius of bigger circle = 8
            Height of frustum = 12
            Slant height of frustum = 13
    Output :
    Volume Of Frustum of Cone : 1218.937
    Curved Surface Area Of Frustum of Cone : 449.24738
    Total Surface Area Of Frustum of Cone : 678.58344
    
    
    Input : Radius of smaller circle = 7
            Radius of bigger circle = 10
            Height of frustum = 4
            Slant height of frustum = 5
    
    Output :
    Volume Of Frustum of Cone : 917.34436
    Curved Surface Area Of Frustum of Cone : 267.03516
    Total Surface Area Of Frustum of Cone : 735.1321
