Answer:
20 millimeters.
Step-by-step explanation:
To find the radius of a circle with circumference, you must divide the circumference by pi (3.14).
After dividing the circumference by pi, you now have the diameter of the circle.
Secondly, to get the radius, divide the quotient (the diameter) by 2.
The quotient is the radius of the circle.

Now, I will repeat these steps using the circumference of 125.6 millimeters.
125.6 ÷ 3.14 = 40.
40 ÷ 2 = 20.
Therefore, 20 millimeters is the radius of this circle.
The circle's radius is mathematically given as
r=20
Question Parameter(s):
The circumference of a circle is 125.6 millimeters.
Generally, the equation for the circumference is mathematically given as
C=2\pi r
Therefore
C=2 *3.14*r
125.6=2 *3.14*r
r=20
In conclusion, The raduis
r=20
