Find the area of the blue sectors formed by angle DFE. Round answer to

iren2701 [21]

Answer:

<h2>1525.7 square meters, approximately.</h2>

Step-by-step explanation:

Notice that the radius is 28 meters, and the angle of the orange sector is 137°. However, the angle of the blue sector is:

360° - 137° = 223°

The area of a circular sector is

$A=\frac{\pi r^{2} \alpha}{360\°}$

Replacing given values, we have

$A=\frac{(3.14)(28)^{2} (223\°)}{360\° }=\frac{548972.48}{360} \approx 1525$

Therefore, the right answer is the second choice.
