I agree that 4 quarters make a dollar. How did they make the dollar knowing that it could be made out of 4 quarters? Dollar sixers can't deny this! Silly one sixers! You can't cut a dollar into six pieces!

Anyways, to answer your Question, the planet we exist on is a sphere and not round. The Area called earth we reside in is a round plane upon that planet. So yes, I agree with you that the earth is round, but the planet Earth is a sphere.

See how you don't even know what it is you are saying? You don't know what the word round means, you don't know what the word earth means.

Now, how about you copy paste this 'formula' you keep eluding to, yet never using to support your 'arguments'.

Edit: I'm currently imagining you scrambling about the internet, searching for this great unifying "sky formula" that you have imaged, that makes it so we can't observer stars if we are standing on a flat surface. Can't wait to see what you post! The anticipation is palatable!
