C would be the right answer
Area of circle, πr² = 452.16
πr² = 452.16
r² = 452.16/π, π ≈ 3.1416
r = √(452.16/π) = √(452.16/3.1416) ≈ 11.997
Circumference = 2πr
C = 2*3.1416*11.997
C ≈ 75.38
Circumference is ≈ 75.38 m.
Hope this helps.

Answer:
This is an arithmetic sequence with a common difference <em>d</em> of -9
Step-by-step explanation:
When you find out <em>d</em>, you realize the difference between the numbers to be -9. Since it is <em>d</em> and not common ratio <em>r</em>, it is an arithmetic sequence.
