What is the area and circumference of a circle that has a radius of 6.8 feet?

-- 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)

If i'm correct the answer is $15.97
