Equatorial Calculation

Equatorial Calculation | A rope around Earth equator need only 2 meters more in length to rise 31cm from equator. Radius of Earth at Equator = R
Circumference of Earth at Equator = C 

C = 2 × pi × R

So using calculus, we can see how much C changes when R changes (we don't need to know the actual radius of Earth at Equator): 
dC = 2 × pi × dR 

So if dR = 31
Then dC = 2 × pi × 31 = 194.779....

So 195cm or 1.95m is more accurate though. | image tagged in flawed logic blank,equator,rope,earth,logic | made w/ Imgflip meme maker

What an interesting way to say "distributive property".
