Y'all are mean. //content.invisioncic.com/y282845/emoticons/laugh.gif.48439b2acf2cfca21620f01e7f77d1e4.gif Radius squared times the height (IN INCHES) gives you the volume in cubic inches. Divide that by 1728 (one cubic foot) to get the volume in cubic feet.

Ummm forgetting pie??? lol, you can't even do it.................

It's REALLY REALLY simple, how can that honestly not make sense...

(Radius x Radius) 3.14= area. Area x length = volume!!!! volume / 1728 = feet cubed
