GPT 3.5
The circumference of a circle is given by the formula C = 2πr, where r is the radius of the circle.
Given that the radius is 12.8 cm, we can plug this value into the formula to find the circumference:
C = 2π(12.8)
C ≈ 2 * 3.14159 * 12.8
C ≈ 80.42 cm
Therefore, the circumference of the circle to the nearest tenth is 80.4 cm.
