Best Answer

A circumference, C, of 80 feet defines a circle of radius R as

C = 2 pi R

and the area of the circle is A = pi R^2

A = C^2/4pi = 509.55 sq ft

12 time 12 inches = 1 square foot (as there are 12 inches in a foot) 10 times 8 feet = 80 square feet 80 square feet divided by 1 square foot = 80 pavers.

A circle with a radius of 80 inches has an area of 139.6 square feet A circle with a circumference of 40.5 feet has an area of 130.5 square feet

That's a total of 2560 square feet.

8' x 10' = 80 square feet

Area of a circle in square feet = pi*radius2
