Answer: 16.76
Explanation:
1. A circle is 360°, we know the white sections are both 120°.
120° + 120° = 240°
360° - 240° = 120°
Therefore the shaded section is 120°
2. Using A = πr^2, we can find the total area of the circle. We know the radius is 4 from the given data.
A = π (4)^2
A = π (16)
A = 50.27
3. 120° is 1/3 of 360°, so we can divide the area we found by 3 to find the area of the shaded section.
A = 50.27 / 3
A = 16.755
A = 16.76
