Question

The circumference of a circle is approximately 39.25 mm. What is the length of the diameter?

Answer 1

Answer:

12.5 millimeters (mm).

Step-by-step 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).
