So, a 4:1 slope for 100', gets you a 25' high cone. Volume of a cone is 1/3 area of the base times the height. 100x100x3.14x25 = 785,000 cf / 27= 29,000 CY. That might be overdoing it a bit. The material I saw on the internet also said at a 4:1 to limit the slope distance to about 50'. Here, we're talking about over 100'. To build a smaller hill, keeping the 4:1 and limiting the slope distance to 50 feet, you'd have a vastly different answer= 50x5Ox3.14*12.5 = 98,000 cf= 3,600 CY In the end,you probably don't want to build a perfect cone. You want to have a hill with different slopes for different ages. So, maybe we've concluded that you need a minimum of about 4,000 CY to start and you certainly don't want any more than 30,000 CY. Hope this helps.
