Cone Lateral Area: π * radius * Length

Cone Total Area: L.A + π * radius^2

Cone Volume: 1/3 π * r^2 * h

Please check your formula for "cone lateral area." See": http://www.bing.com/search?q=cone+lateral+area&src=IE-SearchBox&FORM=IESR02&pc=EUPP_UE02 Find the area of the teepee, not including the base. Divide that area by "15 sq. ft." The result, rounded up to the nearest integer, is the # of skins needed to cover the teepee.
