* As = 77256 cm² ** As = 13.7344 m² *** 18.8496 cm²
**** As = 32 m² ***** As = 49.0875 cm²
Explicación paso a paso:
* As = Acu - Aci ( la parte no sombreada forma un círculo completo )
As = L² - π r²
As = 6² - ( 3.1416 ) ( 3 ) ( 3 ) = 36 - 28.2744 = 7.7256 cm²
** As = Acu - Aci
As = L² - π r²
As = 8² - ( 3.1416 ) ( 4 ) ( 4 ) = 64 - 50.2656 = 13.7344 m²
*** As = Aci - ( Asc + Assc ) = π R² - ( π R²/2 + π r²/2 )
= (3.1416) (4)(4) - {(3.1416 ) (4) (4)/2 + (3.1416)(2)(2)/2}
As = 50.2656 - ( 25.1328 + 6.2832 ) = 18.8496 cm²
**** Si se coloca el semicírculo sombreado en el hueco queda sombreada la mitad del cuadrado , entonces
As = L²/2 = 8²/2 = 64/2 = 32 m²
***** As = Asc + Assc = π R²/2 + π r²/2
As = (3.1416)(5)(5)/2 + (3.1416)(2.5)(2.5)/2
As = 39.27 + 9.8175 = 49.0875 cm²
