Circumference of circle, C = 2πr
C = 2*π*r
C = 2*3.14*6
C = 37.68
Circumference, C = 37.68 feet.
The given radius is in whole number which is zero decimal places.
So one more decimal place is = 1 decimal place.
C = 37.68 ≈ 37.7 to 1 decimal place.
The 1 decimal place digit is 6, and after that is 8, since 8 is more than 5, we add 1 more to the 6 and it becomes 7.
C ≈ 37.7 to 1 decimal place.
