Calculate the area of this figure to the nearest hundredth. use 3.14 to approximate pi
zaharov [31]

Answer:

49.132 m²

Step-by-step explanation:

Area of a triangle=1/2(base×height)

Area=1/2(6×8)

Area=24 m²

Now

Area of semi circle=πr²/2

Area=(3.14)(8÷2)²/2

Area=(3.14)(4)²/2

Area=(3.14)(16)/2

Area=50.265/2

Area=25.132 m²

Now

Total area=area of triangle+semi-circle

Total area=24+25.132

Total area=49.132 m²
