If you mean the diameter and the circumference of a circle:
The ratio called pi - equal to 3.14159265 ... (It's a transcendental number that can never be calculated exactly and the decimal part has no recurring sequence. It has been calculated to more than 10 billion decimal places but 22/7 is close enough for most purposes.)
The circumference is pi times the diameter.
If you want the relationship between the diameter and the circumference of any other regular polygon, then it varies and approaches pi as the number of sides increases. It's usual to give the ratio as a function of the radius because with a finite number of sides, the calculation depends on the length of the side of each segment and the angle of the segment (each segment being an isosceles triangle with the long sides equal to the radius of the circumscribing circle). This, in fact, was one of the ways that pi was originally calculated.

the relationship between diamter and circumfernce is the relationship btween a straight line and a curved one.
The 1st one will take you away from where you are
The 2nd one will curve like a circle and bring you back to where you started.
So does one travel the straight and narrow or take a more circuitous route in life?
The relationship between the two means they cross paths only twice, At the beginning, the middle and the end.
With the Earth as an example, the distance an airplane travels following the equator all the way around the Earth... would be the circumference.
Now if you cut the Earth in half along the equator then the longest straight line distance from one side to the other would be the diameter.
What fun ey! good luck with your math

The circumference is distance around the outside of the circle and the diameter is the distance across.
In math terms the relationship is express as "Pi" or approximately 3.14159 (keeping in mind that Pi is an infinite number and the decimals continue on forever).
It was discovered that the ratio between the diameter of a circle and the circumference was constant. What this means is that you can multiply the diameter of a circle by a special number that is just over 3 to find the distance around the outside. This number is the same, no matter how big the circle is.
circumference = Pi * diameter
The diameter is twice the radius (as the radius measures from the centre to the outside of a circle, and the diameter measures straight across the circle through the centre) so this equation can be written as:
circumference = Pi * 2 * radius

The diameter is the distance that cuts through the center of a sphere. The circumference is the total distance 360 degrees around the edge of this sphere. i.e.-a circle is at it's center most point sliced by a line=diameter. This is then measured from end to end. That is the diameter. The circle is measured on its edge from the same point all the way around its edge coming back to the same point. That is a circumference. The relationship is then pi-3.14- times diameter = the circumference.

think of you're finding at some gasoline in a vacuum container, rather p.c. up. you will see that this gasoline has 10 million molecules and the dimensions of the container is a million cm cubed (i.e. it rather is width, height and intensity are all a million cm). Now, if we argue that a hundred million molecules of gasoline weigh one milligram, the MASS of the gasoline is 0.a million milligrams. The DENSITY of the gasoline is 0.a million milligrams according to cubic centimeter. Now, think of you by some skill take all this gasoline out of the container, and positioned it right into a bigger container, one that is two cubic centimeters in quantity. The mass of the gasoline is the same, you nevertheless have 10 million molecules, which nevertheless have a mass of 0.a million grams. although, the molecules now have two times as plenty area to go around in, so the density is halved. we've got 0.1mg in 2 cubic centimeters, so our density is now 0.05 mg according to cubic centimeter. In end then: Mass is the quantity of stuff that's there, the quantity of stuff that an merchandise is composed of. length is the quantity of area the object takes up (in our occasion, it rather is the dimensions of the vacuum container) Density is the quantity of stuff that's in a definite element of area, and can be calculated via dividing the mass of an merchandise, via it rather is length.

They both pertain to circles. The diameter is the distance from one point on the circle to another point on the circle drawn right through the center. The circumference is the total distance all the way around the circle from point A back to point A

The diameter of a circle is the distance across the center, while the circumference is the distance around the circle. The equation to find the circumference using the radius (half of the diameter), is 2PiR, Where R is the radius.
