1 cubic yard = 27 cubic feet
Volume of a cylinder = (pi) R2 H
R = radius = 1/2 diameter = 1.5 ft
H = height = 40-ft
Volume = (pi) (1.5)2 (40) = 90 pi = 282.743 cubic feet = 10.472 cubic yards (rounded)

How many yards of sand to fill a hole that is 4 feet wide and 20 feet deep?
If the hole is 4 foot square 4' wide by 4' long by 20' deep, then I assume that you are after cubic yards. Multiply the width by the length by the depth and then divide by 27. This would give you the answer in cubic yards. 11.85 cubic yards.If the hole is round:Volume of a cylinder is Pi *R2 * H In this case: 3.14 X 22 X 20 = 251.2 cubic feet there are 27 cubic feet in a cubic yard (3x3X3=27) 251.2 cubic feet / 27 cubic feet per cubic yard = 9.3 cubic yards
