The formula for the volume of a cylinder is V=pi*r2*h.
r=d/2 = 14ft/2 = 7ft, r2 = 49ft2. h = 3 inch/(12inch/ft) = 0.25 ft.
so V = pi*49ft2*.25ft = 38.48ft3.
You will need 65.93 cubic yards or 84.6 tons of gravel.
Plan on about 2.2 cubic yards (2.8 tons) of gravel.
You will need 20 cubic yards or 25.7 tons of gravel.
Tell me more about the number "6"? is that feet or inches?
(2222/9) times (the weight of 1 cubic yard of gravel, in tons)
1 371.42857 US gallons or 5.19142188 cubic meters
218.75 cubic feet or 8.1 cubic yards
50 cu. fts or 1.8518 cu. yds.
16' x 16' x 0.5' = 128 cubic feet
3000 sq ft * 4 inches = 1000 cubic feet.
The answer will depend on the depth to which the gravel is to be spread.
2 inches = 1/6 foot Volume = 3,500/6 = 5831/3 cubic feet = 21.605 cubic yards
