The circumference of a circle can be calculated using the formula C = 2πr, where C represents the circumference and r is the radius.
In this case, the radius r is 6. Plugging this value into the formula gives:
C = 2π(6)
Calculating this, we find:
C = 12π
To get a numerical approximation, we can use the value of π (approximately 3.14):
C ≈ 12 × 3.14 = 37.68
So, the circumference of a circle with a radius of 6 is approximately 37.68 units.
