Well, I asked my math teacher and thi is what she said. Okay. A long time ago there were math mathematicians. They had circles sculpted out of rock and wood and stuff like that. So anyway, these mathematicians, or MAs would study the circles by mesuring them. The MA's would take a tape and measure all the way around a circle. They then would measure across the circle. The would do big circles and small circles. They then noticed that there was a pattern. If the mutiplied the distance across the circle times a number, they would get the circumferance. The number was, 22/7 or 3.14...and pi was born. So of course we know that the decimal isn't perfect and we won't get an exact answer when mutipling by pi. But now at least we don't have to cut a circle out of stone and use a measuring tape to determine it that way. ~Minicooper Out!

What is Circle pi relationship?
Pi ( 3.142 approx.) is the amount of times the diameter of a circle can be measured along the circumference of a circle. We know that Pi multiplied by the diameter of the circle is equal to it circumference. So we write C=PiD This means, as it says above, that a certain number of "Pi's" will be equal to the circumference.
If the diameter of the circle above is 10 meters what is the circumference of the circle?
Circumference is equal to Diameter x Pi. So the circumference is 10π
The ratio of the circumference of a circle to its diameter roughly equal to 3.141592?
Circumference (C) = diameter (D) times pi (3.141592) is the ratio of the circumference of a circle to its diameter.
What is the circumference of the circle with a 12inch diameter?
The circumference is equal to pi ( 3.14167... ) times the diameter. You do the math.
Is the diameter half of the circumference?
No. The diameter is twice the radius. The circumference is equal to the diameter multiplied by pi (3.142). So the diameter is just under 1/3 of the circumference.
