18ft is equal to 6 yards so a square of 6yds x 6yds would have an area of 36 square yards.
18ft= how many yards
18 feet = 6 yards
That depends on how thick you want it. Multiply 18ft * 18ft * thickness (in units of feet). That will give you your volume in cubic feet. To convert it to cubic yards divide your answer by 27.
If the diameter is 18 ft then the radius is 9 ft = 3 yards. Then the area is pi*r2 = 28.27 sq yards.
