Answer 1

FIGURA 1

Acuadrado = LxL

Ac = (9cm)(9cm)

Ac = 81cm²

Acírculo = πr²

Ac = π(4cm)²

Ac = π(16)cm²

Ac = 50.27cm²

Asombreada = Acuadrado - Acírculo

As = 81cm² - 50.27cm²

As = 30.73cm²

FIGURA 2

Acírculo = πr²

Ac = π(12cm)²

Ac = π(144)cm²

Ac = 452.39cm²

Arectángulo = bxh

Ar = (3cm)(10cm)

Ar = 30cm²

Asombreada = Acírculo - Arectángulo

As = 452.39cm² - 30cm²

As = 422.39cm²

FIGURA 3

Arectángulo = bxh

Ar = (8cm)(7cm)

Ar = 56cm²

Acírculo = πr²

Ac = π(3cm)²

Ac = π(9)cm²

Ac = 28.27cm²

Asombreada = Arectángulo - Acírculo

As = 56cm² - 28.27cm²

As = 27.73cm²

FIGURA 4

Acírculo = πr²

Ac = π(5cm)²

Ac = π(25)cm²

Ac = 78.54cm²

Acírculo = πr²

Ac = π(3cm)²

Ac = π(9)cm²

Ac = 28.27cm²

Asombreada = Acírculo - Acírculo

As = 78.54cm² - 28.27cm²

As = 50.27cm²
