Question

calcule el área y el volumen de un cilindro.
R = 3cm y H = 8cm

Answer 1

Explicación paso a paso:

Datos

r = 3 cm

h = 8 cm

Fórmula

• A total = 2 Π r ( h + r )
• V cilindro = Π r² · h

Sustitucion y Resultado

A total = 2 Π · 3 cm (8 cm + 3 cm)

A total = 2 Π · 3 cm (8 cm + 3 cm) A total = 6 Π cm (11 cm)

A total = 2 Π · 3 cm (8 cm + 3 cm) A total = 6 Π cm (11 cm) A total = 66 Π cm²

A total = 2 Π · 3 cm (8 cm + 3 cm) A total = 6 Π cm (11 cm) A total = 66 Π cm²A total = 66 Π cm²

A total = 2 Π · 3 cm (8 cm + 3 cm) A total = 6 Π cm (11 cm) A total = 66 Π cm²A total = 66 Π cm²A total = 66 x 3,14

A total = 207,24 cm²

V cilindro = Π (3 cm)² · 8 cm

V cilindro = Π (3 cm)² · 8 cm V cilindro = 24 Π cm³

V cilindro = 75,36 cm³
