Question

Find the area of the shaded region. The length of AC is 10 meters and the m angle CAD=140 degrees . Round your answer to the nearest tenth (don't include units).

Answer 1

Answer:

122 m²

Step-by-step explanation:

Radius r = 10 m.

For a whole circle, the area is πr², that is for 360° at the center.

Now the angle is 140°, so the area of the shaded region is (140/360) πr² = 140 * 3.14 * 100/360 = 122 m²
