The ratio of the circumference to the diameter is [tex]3.14:1[/tex]
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 [tex]12.57:4[/tex]
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,
[tex]C=\pi d[/tex]
[tex]\pi = \frac{C}{d}[/tex]
where C is the circumference and d is the diameter.
Thus, we get,
[tex]\pi=\frac{12.57}{4}[/tex]
[tex]\pi=3.1425[/tex]
[tex]\pi=3.14[/tex] (app.)
Thus, the ratio is the circumference to the diameter is [tex]3.14:1[/tex]
