Comment on Let π = 5
jordanlund@lemmy.world 6 months agoWell, a r=10 and h=10 doesn’t mean much without units. 10 what? Feet? Meters? Inches? CM?
Let’s take the OG numbers and assume feet, so 5,000 cubic feet. That’s not a useful volume measurement.
1 cubic foot of water = 7.48052 gallons
So 5,000 cubic feet of water = 37,402.6 gallons. That’s a viable volume measurement.
1 cubic meter = 1,000 liters.
5,000 cubic meters = 5,000,000 liters.

Its not supposed to mean anything, it’s about the equation not about the end result. We’re not calculating an actual cilinder

If we’re not calculating something useful, then why are we here and not in the library learing about the universe?
Better question: What curvature of space is necessary for the apparent value of π to be 5?
MinekPo1@lemmy.ml 6 months ago
honestly I don’t know if there is any way to measure curvature of space , but its slightly more curved than the surface of a ball (where π=~4.712)

Kind of curious how you got that value. I think the ratio of circumference to diameter (“pi”) is actually smaller in spherical geometry, in the most extreme case (the equator) it’s just 1. You could say “pi = 5” for circles of a specific radius in hyperbolic geometry, I guess.
