A 30 foot circle covers about 707 square feet. 23 pieces would technically cover that. I'd get 30 of them so I wouldn't have to cut any of them.
A 16-foot circle has an area of 201.06 square feet.
To cover a 27-foot round circle, first calculate the area of the circle using the formula (A = \pi r^2), where (r) is the radius (13.5 feet). This gives an area of approximately 570.58 square feet. Each 4'x8' square has an area of 32 square feet. Dividing the area of the circle by the area of one square, you will need about 18 squares to cover the circle.
The area of a 17-foot circle is: 227 square feet.
The circumference of a 128-foot diameter circle is: 402.12 feet.
