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
