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)
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.
The circumference of a circle equals pi times the diameter.
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.
Because the ratio of the circumference of any circle to its diameter is pi.
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.
