Hello,
8*√3 is the side.
The height is √((8√3)²-(4√3)²)=√(64*3-16*3)=12
Area of the triangle=8*√3*12/2=48√3≈83

Answer:
![SA=514,457,600\ km^{2}](https://tex.z-dn.net/?f=SA%3D514%2C457%2C600%5C%20km%5E%7B2%7D)
![V=1,097,509,546,667\ km^{3}](https://tex.z-dn.net/?f=V%3D1%2C097%2C509%2C546%2C667%5C%20km%5E%7B3%7D)
Step-by-step explanation:
step 1
Find the surface area
we know that
the surface area of a sphere is equal to
![SA=4\pi r^{2}](https://tex.z-dn.net/?f=SA%3D4%5Cpi%20r%5E%7B2%7D)
substitute
![SA=4 \pi (6,400)^{2}](https://tex.z-dn.net/?f=SA%3D4%20%5Cpi%20%286%2C400%29%5E%7B2%7D)
substitute the approximate value of pi (3.14)
![SA=(3.14) (163,840,000)](https://tex.z-dn.net/?f=SA%3D%283.14%29%20%28163%2C840%2C000%29)
step 2
Find the volume
The volume is equal to
![V=(4/3)\pi r^{3}](https://tex.z-dn.net/?f=V%3D%284%2F3%29%5Cpi%20r%5E%7B3%7D)
substitute
![V=(4/3)(3.14) (6,400)^{3}](https://tex.z-dn.net/?f=V%3D%284%2F3%29%283.14%29%20%286%2C400%29%5E%7B3%7D)
![V=1,097,509,546,667\ km^{3}](https://tex.z-dn.net/?f=V%3D1%2C097%2C509%2C546%2C667%5C%20km%5E%7B3%7D)
