300 square feet.
Five--a roll will cover 400 square feet of area.
The area of a circle with a diameter of 18 feet can be calculated by: A=pie x r x r . So, in this case A = 3.14 x 9 * 9= 255 square feet. If you know how many square feet are in a roll of sod, you can find your answer.

1 square = 100 square feet x 8 squares = 800 square feet. 15# felt comes in different sizes. Multiply the length of the roll x the width of the roll to find out how many square feet are in a roll. 800 divided by the square feet per roll = how many rolls you need.

Easy way to figure it: If the roll is 3 feet by 100 feet, it would cover 300 square feet. But you have to overlap it about 6 inches at top and bottom, so once you subtract that, it would cover about 200 square feet., When figuring a job, add some for overlap at valleys, chimneys, etc. . . Hope this helps. A standard roll of 30# felt covers 216 square feet; one-half the area of a roll of 15# felt, which covers 432 square feet. Rows are overlapped 2 inches, not 6 inches.
