What is the circumference of a circle with a radius of 16 cm?

The circumference of a circle can be calculated using the formula C = 2πr, where C is the circumference, π is the mathematical constant pi (approximately 3.14159), and r is the radius of the circle. In this case, the radius is 16 cm, so the circumference would be C = 2 x π x 16 cm = 32π cm, or approximately 100.53 cm.
