Answer

15.7 meters squared.

Step-by-step explanation:

First you have to find the area of the small circle, using the formule A = 3.14(radius squared). So, 3.14(4) =12.56. Then you have to find the area of the bigger circle. A = 3.14(3 squared). A = 3.14(9) = 28.26. Finally, you subtract the area of the smaller circle from the bigger circle. 28.6 meters - 12.56 meters = 15.7 meters squared.

Lena [83]
Based on the given problem above, it requires a trigonometric solution. So here it goes:
The climb distance is:<span>200 * Sec <span>[<span>ArcTan <span>[10/200]</span></span>]</span> = 10</span>√ 401 km
and the decent distance is:<span>300 * Sec <span>[<span>ArcTan <span>[<span>10/300</span>]</span></span>]</span> = 10</span>√901 km
So add the given results above with 500 km and this will be the additional distance that <span>plane moves through the air.
The answer would be in the unit meters.
</span><span>(<span>(10</span></span>√401 +10√901−500)∗1000)=416 meters
Hope this is the answer that you are looking for.

PolarNik [594]

The area of a sector is 339.336 cm²

The area of a sector is defined to be as the region of space bounded by a boundary from the center of the circle.

It can be determined by using the formula:

\mathbf{A = \dfrac{\theta }{360}\times \pi r^2 }

Given that;

  • Radius r = 18 cm
  • Angle θ =  120°

Then. the area of the sector can be calculated as:

\mathbf{A = \dfrac{120}{360}\times \pi (18)^2 }

\mathbf{A = \dfrac{1}{3}\times 3.142 \times 324 }

A = 339.336 cm²
