1-conseguir area de cuadrado
Acua =L^2
Acua = (6)^2 = 36 cm^2
2-conseguir el area del círculo dentro, sabiendo que su diametro es L y el radio es L/2
r= L/2 = (6)/2 = 3
Acir = pi*r^2
Acir = pi*(3)^2 = 28.27cm^2
3- por ultimo, restas al area del cuadrado el area del cubo, y habras hallado el area sombreada.
At = Acua - Acir
At = 36 - 28.27 = 7.73cm^2
Saludos!
