Estimating the wood in a pile

I just finished splitting my 2010 wood and it is now in 3 big piles around my house, ready to get stacked this weekend. Since Geometry was many, many years ago.I'm wondering if there is a way to estimate how much wood is in a pile. For instance, if the base has a diameter of 10 feet and the pile is 5 feet tall, how many cords will that be. I know the slope of the pile will vary but I would guesstimate it at around 50 degrees.

Any math whizzes out there?

Take a picture....post it for us, and then we can guess.
Then, you can give a free round to the closest guesser.

Use the volume of a cone. 1/3 pi r^2 h
r= radius
h= height

so in this case v= 1/3 (3.14) (5 sqared) * 5 = 1/3 *3.14 *25 *5

Divide by 128 to find cord

That will prolly be a conservative estimate- most piles are rounded a bit

W/o crunching numbers or seeing a picture, it sounds like it's about 1.25 to 1.5 cords.

sounds about right i just stacked today with about those same dimensions and got around 1.5 cords

i estimate that you have 3 piles of wood.
