The ratio of the circumference to the diameter is
3.14:1

Step-by-step explanation:

It is given that a circle with diameter of 4 cm and circumference is 12.57 cm

The ratio of the circumference to the diameter is
12.57:4

We need to determine the ratio of the circumference to the diameter.

Let us substitute the values in the circumference of the circle formula.

Thus, we have,

$C=\pi d$

$\pi = (C)/(d)$

where C is the circumference and d is the diameter.

Thus, we get,

$\pi=(12.57)/(4)$

$\pi=3.1425$

$\pi=3.14$ (app.)

Thus, the ratio is the circumference to the diameter is
3.14:1
