Answer:
Sir Francis Drake was the first englishman to circumnavigate the globe.
Explanation:
However, he was not the first European. Ferdinand Magellan is often credited with this but he died during the voyage and Sebastian Elcano took over the expedition. They sailed about 50 years earlier than Sir Francis Drake.
Radius of earth as given in question = 6400 km
Height of the air balloon = 200 m
= 0.20 km
Now
Let us assume the distance up to which one can see from the balloon = d
Then
d=sqrt [<span><span><span>(R+h<span>)2</span>−<span>R2]
</span></span></span> = sqrt [</span><span><span>2Rh+<span>h^2]
= sqrt [2 (6400 * 0.20) + (0.20)^2]
= sqrt [(2 * 1280) + 0.04]
= sqrt [ 2560 + 0.04]
= sqrt [2560.04]
= 50.6 km
A person in the balloon can see up to a distance of 50.6 km. I hope the answer has helped you.</span></span></span>
