What's the volume of a cylinder 6 ft high with a 20 ft diameter?

[arcadian]

In gallons.

[Richardo]

1. I say about 1800

L * 3.14*(r*r)

6 * 3.14*(10*10)

6 * 314

1884 cu ft

1 gallon of milk comes in a container a little less than 1 cubic foot.

3. 1800 gallons?

gotta be more than that, thanks

[Richardo]

13. PoliSci majors should never do math in their heads

:blush:

[Rabrrrrrr]

15. No. No they shouldn't. No ever. Not ever ever ever.

Not if they're gonna come up with "1800 gallons" for something that monstrous.

:P

2. 1187

or so

I think

4. 14,130 gallons?

God, I need to practice my math skills more often. I'm losing it.

Volume = 0.785 * D^2 * H
= 0.785 x 20ft² x H
= 0.785 x 400ft² x 6ft
= 314ft² x 6ft
= 1884ft³


Conversion factor
1 cubic foot = 7.5 gallons

1884 * 7.5 = 14130 gallons

5. I think it's closer to 10,000

but I need a better number.

[Jamastiene]

8. I edited the other post, but I'll repeat it here with the actual

calcs to see if I am closer now.

Volume = 0.785 * D² * H
= 0.785 x 20ft² x H
= 0.785 x 400ft² x 6ft
= 314ft² x 6ft
= 1884ft³


Conversion factor
1 cubic foot = 7.5 gallons

1884 * 7.5 = 14130 gallons

16. Not sure how exact the OP needs this but

7.5 gallons per cubic foot is a common estimate. It is actually 7.48 and some change. So, I come up with around 14,092 gallons.

12. Woot!

:woohoo:

I love math.

[baldguy]

6. Now i've got it!

vol of a cylinder = Pi * r^2 * h = 3.14~ * 20^2 * 6 = 7539.82 cu ft

1 gal = 0.13368 cubic feet

7539.82 / 0.13368 = 1007.92 gal

7. Easy

1885.7 metres, converted to 498.281199 U.S. gallons.

You really should do your own homework, you know.

10. 120 * PI cubit feet

Roughly 1183 cu. feet.

[JVS]

11. Figure it out in cubic feet and then convert to gallons.

17. However much makes it full...
