Question

If you know the circumference how do you figure out the diameter

Answer 1

To find the diameter of a circle when you know the circumference, divide the circumference by π.

Step-by-step explanation:

To find the diameter of a circle when you know the circumference, you can use the formula:

diameter = circumference / π

where π is approximately 3.14159...

For example, if the circumference of a circle is 20 units, the diameter would be:

diameter = 20 / π ≈ 20 / 3.14159 ≈ 6.37 units

Answer 2

radius times 2

Step-by-step explanation:

The circumference is 2πr.

Here is what you do:

1. Circumference/ 2π to solve for r, which is radius

2. 2 x r will equal to the diameter
