Question

Calcula el área de la siguiente figura:

Answer 1

Tenemos.

Area sombreada = As
L = Lado del cuadrado = 4cm
Radio = r
Area1 + Area 2 = Area de medio circulo de radio r = 2cm

As = Area de CuadradoABCD -  Area de medio circulo
As = L * L - πr²/2
As = (4cm)(4cm) - π(2cm)²/2As =
As = 16cm² - 4πcm/2
As = 16cm² - 2πcm²             Factorizamos el 2
As =  2(8 - π)cm²

Respuesta.

As = 2(8 - π)cm²

Answer 2

Respuesta:

As = 2(8 - π)cm²
