The radius of a circle is 16 millimeters what the circumstance use 3.14 for pi

The circumference of the circle is:

C = 2πr

C = 2(3.14)(16)

C = 100.48 millimeters

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

Circumference = 2 * π * radius

Given the radius is 16 millimeters and we can use 3.14 for π, we can substitute the values into the formula:

Circumference = 2 * 3.14 * 16

Performing the calculations:

Circumference = 100.48 millimeters

Therefore, the circumference of the circle is 100.48 millimeters.
