The distance from Alexandria to Syene is about 500 miles. On the summer solstice the sun is directly overhead at noon in Syene.
svp [43]

Answer:

Earth circumference is 25000 miles

correct option is 25,000 miles

Explanation:

we have given here Alexandria to Syene distance = 500 miles

the sun is 1/50th of the circumference of the sky (about 7°)

as we know that Earth circumference done by astronomer Eratosthenes in 240 B.C

He observe on a particular time of day ( in noon) during the summer solstice

and there was no shadow in Syene in Egypt so  This was verified that the sun must be directly on overhead and not at an angle to the surface of the city at that time

so

In Alexandria he measured the position of sun at the same time and found it to be nearly (1/50)th of a complete circle

it would be 7.2 degree (when we do \frac{360}{50} = 7.2)

so 2 reference points being 2 cities for the sun

all measure circumference =  the distance between these two cities × 50  

and we have given 500 miles

so

Earth circumference = 500 × 50

Earth circumference is 25000 miles

correct option is 25,000 miles

Which conclusion explains Africa’s economic and government problems after independence
klemol [59]

Along with the fact that the infrastructural and industrial levels of the African colonies was never really developed by Europeans, the many various and opposing ethnic groups had no one to keep them in check now. As a result many civil wars took place between different religions, specific religious denominations, and specific ethnic groups of said religious denominations. Also nearly all of the leaders that broke free of European rule were woefully unprepared to lead a country both governmentally and economically. All of these factors are what lead to Africa's current problems.
