Question

Halla el area de la fig . si π=3.14

Answer 1

Respuesta:

33.12

Explicación paso a paso:

1) area=Πr²/2   +[100(180)/2][50]

area=(3.14)(50²)/2  +50²(180)

area=50²(1.57+180)

area=453.925m²

2) area=Πr²+[8(4)-Πr²]

area=(3.14)(2²)+[32-(3.14)(2²)]

area=12.56+19.44=32cm²

2)) perimetro=4(2)+2(2πr)

per=8+4(3.14)(2)=33.12cm
