Well, with those numbers, it's easy math. :)

V=5*10^2*10

5,000. 5,000 what though?

Even with a proper π value, it still doesn't make sense... 3,141.59265359

What? Its just the volume, without units. What part of it doesn't make sense?

Well, 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

The unit is unit.

The math doesn’t care, and what you’re on about only really matters if the units don’t start as all the same or if you start converting between things.

Literally the correct answer. Must be a bunch of engineers in this thread.

[–] mnemonicmonkeys@sh.itjust.works 7 points 7 months ago

No, engineers wouldn't have a problem with this. This dude is just some rando that has no idea what he's whinging about

Just calculating a cylinder that may or may not have an m&m minis tube stuck on it
