Answer:
Area of the shaded region = 75.36 in^2
Step-by-step explanation:
You find the area of the large circle and divide it in half. You find the area of the small circle and divide it in half. Finally, you subtract the small half circle from the large half circle.
A = area
π = Pi = 3.14
r = radius= the distance from the center of the circle to the edge.
A = π * r * r A = π * r * r
A = 3.14 * 8 * 8 A = 3.14 * 4 * 4
A = <u>200.96</u> A = <u>50.24</u>
2 2
A = 100.44 in^2 A = 25.12 in^2
100.44 - 25.12 = 75.36 in^2
