Flat Earthers, Tell Me What the Diameter of Your Earth Disk Is?

I Shall Provide that for You Now: Behold Some Science

What’s the motivation for this? It is because I cannot find this out on the internet. It wasn’t figured out by Mark Sargent, either. He just says in a video “thousands of miles across.” So, as a scientist, I would like to know how big the Flat Earth disk is. So, here we go.

Our first task in this calculation is to determine the surface area of the earth in the globe model. The formula for the surface area of a sphere is A = 4*pi*r². The radius of the earth is 3,958.8 mi, according to Google. So, we then do the calculation:

A = 4*pi*(3958.8)² = 196,941,384.7 square miles

So, this needs to be the same area as the Flat Earth. The area of a circle is A = pi*r². We know the area, and we know pi. Thus, it is a simple calculation to find the radius, r.

r² = A/pi = 196,941,384.7 / 3.14 = 62,688,389.76 square miles

To get the plain radius, we just take the square root.

r = 7,917.6 miles

So, then, the diameter of the Flat Earth is (drum roll, please dddddddddddd):

diameter = 15,835.2 miles
