Answer: this is what i know

The distance from one side of the circle to the other, going through the center of the circle, is the diameter. The constant pi, designated by the Greek letter π, is the ratio of the circumference to the diameter of a circle. For any circle, if you divide the circumference by the diameter you get pi, an irregular number usually rounded to 3.14.

hope it helps

Answer:

C ≈ 37.68 cm

Ratio:
(circumference)/(diameter)=(\pi )/(1)

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
(C)/(d)=(\pi )/(1)
