So there is two congruent right angle triangles and the distance from the centre of the earth to the satellite is the 6360+720= 7080km
And the radius of the earth is the 6360 which forms one of the other sides of the triangle. So the only missing part is BA so BA = the square root of 7080² - 6360² which equals about 3110.76KM So BC= 3100 rounded to nearest hundredth which it asks you to in the question

2A

Step-by-step explanation:

Please help me how to figure this out I’m trying to figure out the area ASAP please

Natasha2012 [34]

Answer:

$1230.88m^{2}$

Step-by-step explanation:

Shown is one-fourth of a circle. Also, according to the picture, the radius is 28 meters.

The area for a whole circle is $2\pi r^{2}$ .

Using that information, we can find the area as if the circle was whole instead of just the fourth.

$2(\pi)(28m)^2 = 2(3.14)(784m^{2} ) = 4923.52m^{2}$

Now that we know the area of the whole circle, we just have to divide it by four to find the area of the fourth of the circle.

$4923.52m^{2} / 4 = 1230.88m^{2}$

That means that the area of the shape shown is $1230.88m^{2}$ .

I hope this helps!
