Pi, or 3.14159... Using the equation Circumference = pi * diameter.
Infinitely many. Each point on the circumference of a semicircle can be one end of a diameter and there are infinitely many points in a line segment of any length.
It is: circumference/diameter = pi
Diameters don't have "circumference." If you want the circumference of a circle with diameter 18 in, then it is just pi*d = 18pi inches.
You can do an experiment on several circles of different diameters.

circumference = 2 x pi x radius which is the same as pi x diameter so the answer is pi.
A typical circle has an infinite number of diameters. Each diameter is a line segment that passes through the center of the circle and has endpoints on the circumference.
Mars has a diameter of about 6,779 kilometers, and its equatorial circumference is approximately 21,344 kilometers. Therefore, Mars is a little over three diameters away from its equator.

Draw two diameters of the circle and join the points where they meet the circumference.
The circumference of a circle in Euclidean space is pi times the diameter of that circle. Or:If, inside a circle, a lineHits the center and runs spine to spine,And the line's length is D,The circumference will beD times 3.14159. Er, approximately.
