Answer:

Area = 22.3 m^2

Perimeter 27.4 m^2

Step-by-step explanation:

Perimeter = __ m

Area __ m^2

The area of the triangle is about 4.2,

The area of the square is 4,

The area of the semicircle is 14.1,

14.1 + 4.2 + 4 = 22.3

Area = 22.3 m^2

9.4 + 6 + 4 + 4 + 4 = 27.4

Perimeter = 27.4 m^2

Therefore the area of the shape is about 22.3 m^2 and the perimeter is about 27.4 m^2.

Answer:

El área de superficie del cilindro es 6 · π cm², que es igual a 18.85 cm²

El volumen del cilindro es de 9 · π cm³, que es igual a 28.27 cm³

Step-by-step explanation:

Aquí tenemos

El área de superficie del cilindro = Perímetro de base × Altura

= π × D × h

Dónde:

D = diámetro de la base = 1.5 cm

h = Altura del cilindro = 4

∴ Área de superficie = π × 1.5 × 4 = 6 · π cm² = 18.85 cm²

Volumen del cilindro = Área de base × Altura = π · D² / 4 × h

= π × 1.5² / 4 × 4 = 9 · π cm³ = 28.27 cm³.
