Question

El cuadrado de la figura mide 4 cm de lado. Los dos arcos son parte de dos circunferencias. ¿Cuánto mide el área de la figura sombreada? (considera n = 3.14​

Answer 1

$As = 2( A○ - A◢ ) \\ As = 2( \frac{\pi}{4} {L}^{2} - \frac{ {L}^{2} }{2} ) \\ As = 2( \frac{\pi}{4} {2}^{2} - \frac{ {2}^{2} }{2} ) \\ As = 2( \pi - 2 ) \\ As = 2( 3.14 - 2) \\ As = 2( 1.14 ) \\ As = 2.28 \ cm²$

Rpta: a) 2π - 4 = 2.28 cm²
