The conversation between human and AI assistant.
[|Human|] Calculate the circumference of the given circle.
[|AI|] Okay. To calculate the circumference of a circle, we use the formula C = 2πr, where “C” represents the circumference, “π” represents the mathematical constant approximately equal to 3.14, and “r” represents the radius. 

So for a circle with a radius of 10 cm, its circumference is C = 2 x 3.14 x 10 = 62.8 cm
