Pi, or 3.14159... Using the equation Circumference = pi * diameter.
pi or 3.14159265...
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.
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.

Pi (3.1415)
Their circumferences are in the same ratio as their diameters.
circumference = 2 x pi x radius which is the same as pi x diameter so the answer is pi.

It is: circumference/diameter = 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.
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.
As many as you like. Diagonals in a circle are referred to as diameters. A diameter is any straight line drawn from one edge of the circumferencem, through the centre and drawn to the opposite edge of the circumference. There are an infinite number of diameters to a circle. !!!!

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.
