Answer:

12.5 millimeters (mm).

Explanation:

Explain/define:

CIRCUMFERENCE: THE DISTANCE AROUND A CIRCLE.

DIAMETER: THE LENGTH OF A STRAIGHT LINE THROUGH THE CENTER OF A CIRCLE.

Mathematics: Formula


d=c/3.14


d-diameter


c-circumference

Mathematics: Solve

To find the length of the diameter from the circumference, divide the circumference by pi. The quotient is the diameter.

3.14 is often used for pi.


39.25/3.14=12.5.

Conclude:

Therefore, the length of the diameter of the circle is 12.5 millimeters (mm).
