-- The area of any circle is (pi) times (the circle's radius)².
If the radius is 6.8 feet, then the area is (pi) x (6.8)² = 145.27 square feet (rounded)
-- The circumference of any circle is (2 pi) x (the circle's radius).
If the radius is 6.8 feet, then the circumference is (2pi) x (6.8)= 42.73 feet (rounded)
