The answer depends on what the ratio is relative to!The ratio of a circumference to the area of a circle is half the radius.
ratio of circumference to diameter of a circle is 3.14159265:1
The ratio of a circle's circumference to its area is called the reciprocal of half the radius. The ratio of the circumference to its radius is called two times 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)
The ratio of the circumference of a circle to its diameter is Pi. (3.14159)
The ratio of the circumference to the radius of the circle is 2 times pi
the circumference ratio
The ratio of the circumference of a circle with radius 4 cm to its area is 1:2.
Pi is the ratio of circumference to diameter. C/d=pi always!!!
C = pi x D is the ratio of a circle's circumference to its diameter.
Circumference (C) = diameter (D) times pi (3.141592) is the ratio of the circumference of a circle to its diameter.
