The ratio is 1/pi.
The ratio of the circumference of a circle to its diameter is Pi. (3.14159)
The ratio of the circumference of a circle to its diameter is Pi. (3.14159)
C = pi x D is the ratio of a circle's circumference to its diameter.
ratio of circumference to diameter of a circle is 3.14159265:1
Circumference (C) = diameter (D) times pi (3.141592) is the ratio of the circumference of a circle to its diameter.
The ratio of the circumference of a circle to its diameter is Pi. (3.14159)
The circumference of a circle equals pi times the diameter.
Pi is, by definition, the ratio of a circle's circumference to its diameter. It follows that the circumference of any circle is pi times its diameter.
Because the ratio of the circumference of any circle to its diameter is pi.
The ratio between the diameter of a circle and its circumference is constant: π. A circle whose circumference measures 3 feet has a diameter of 3/π feet: approximately 11.459 inches.
The circumference of any circle is: diameter times pi The circumference of any circle divided by its diameter is the value of pi
It was originally noticed as the ratio between the circumference of a circle and its diameter.
