C ≈ 37.68 cm
Ratio:![\frac{circumference}{diameter}=\frac{\pi }{1}](/tpl/images/0323/5582/9a8c5.png)
Step-by-step explanation:
The general formula for circumference is diameter times pi, or
C = dπ, where d = diameter
In this case, the diameter = 12cm;
C = 12π ≈ 37.68
To find the ratio of circumference to the diameter, we can use the formula:
C = dπ or![\frac{C}{d}=\frac{\pi }{1}](/tpl/images/0323/5582/3b59c.png)
