Since the celestial body has the shape of a ball, the length of the equator is the circumference.
The circumference is found using the law: l = 2πr = πd, whence the diameter will be d = l / π.
If the length of the equator is 10.9 thousand km or 10,900 km, then the diameter has a length:
10900 / 3.14 = 3471 (km) ≈ 35 (hundreds of km)
Answer: the diameter of the Earth’s satellite is approximately 35 hundred kilometers.
