Draw me a right triangle if you would . Small side is 25 . Hipopotimus is 3950 . Need the large side .

I know A squared + B squared = C squared , divided by 2 = the hippopotimus .

Trying to find out how much rise of a curve of the earth I see in a 50 mile distance across the horizon .

I don't have a trigonomic calculator here . TIA

Not 'divide by 2', the square root of two,
If you are standing perpendicular to the earths surface (and you assume there are no variations in ground level), the Earth will appear to fall away from you.
Based on the figures you gave, the 'other' side is 3949.92 - 0.08. What is the 3950 figure based on?

Just clicked, the average radius of the earth in miles.
That will give the 'other' side as 422.4 feet.

Only needs a relatively simple calculator. Got one on your phone?

(apologies for the typo in the first reply:confused:)

Thanks everyone . What brought this up was the old theory the world was flat when the explorers went out . I told my sister I could see the earths curve on the balcony over 50 miles . So if the explorers had a straight surface and a clear line of the horizon , they would see the world wasn't flat .

Just more useless information for today ! :grin:

The world was flat when they went out.

But the weight of the explorers caused the earth to sag at the edges and…. Ummm…..


Yeah.
