In a circle with radius 6, what is the circumference? (C = 2πr)

The circumference grows with the radius in a circle according to C = 2πr. Plugging in r = 6 gives C = 2π(6) = 12π. Using π ≈ 3.1416, that’s about 37.699, which rounds to 37.70. So the correct value is 37.70. The other numbers don’t match 12π or its typical rounding.
