Find the area of the composite shape. Use 3.14 for ni and round to the nearest hundredth.
Nonamiya [84]

Answer:

49.12 square inches

Step-by-step explanation:

Area of a circle = Pi x r^2

= 3.14 x 4^2

= 3.14 x 16

= 50.24

Half the circle = 25.12 squared inches

Area of a triangle = base x height /2

= 6 x 8 /2

= 24

25.12 + 24 = 49.12 square inches
