Question

Find the area of the shaded section

Answer 1

Answer:

120

Step-by-step explanation:

Answer 2

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
