Question

ayuda es de geometria es areas sombreadas

Answer 1

Respuesta:

53,76 centimetros cuadrados

Explicación paso a paso:

a = lado menor del rectangulo

b = lado mayor del rectangulo

r = radio del circulo

a = 8 cm

b = 13 cm

Del Grafico:

r = a / 2

r = 8 / 2

r = 4 cm

A₁ = area del rectangulo

A₂ = area del circulo

As = area sombreada

Formula:

A₁ = ab

A₁ = 8(13)

A₁ = 104 cm²

Formula:

A₂ = r²π

A₂ = 4²π

A₂ = 16π

A₂ = 16(3,1416)

A₂ = 50,2656

A₂ = 50,27 cm²

Luego:

As = A₁ - A₂

As = 104 - 50,27

As = 53,73 cm² (aproximado)
