I gave her a link to the math to calculates the curve properly, but she's stuck on a flat earther's bogus equation. Someone told me the flat earther's math is actually based on archaic surveying approximations.
Sorry about the poor quality image.
But . . . . .
My math is the same as your math.
Did you even read your link???
Here is your link.

Accurately calculate the curvature you are supposed to see on the ball Earth.
Distance: Kilometers Miles Calculate
3 miles = 0.67 feet
2 miles0.00051 miles = 2.67 feet
5 miles0.00316 miles = 16.67 feet
10 miles0.01263 miles = 66.69 feet
20 miles0.05052 miles = 266.75 feet
50 miles0.31575 miles = 1667.17 feet
100 miles1.26296 miles = 6668.41 feet
200 miles5.05102 miles = 26669.37 feet
500 miles31.5336 miles = 166497.53 feet
1000 miles125.632 miles = 663337.65 feet
You have all the data, all the figures, the formula at your disposal. With that data, please tell us the diameter of the Earth with the curvature figures you supplied .
