The number pi can be defined as: pi = circumference / diameter. Solving for diameter: diameter = circumference / pi. Pi is approximately 3.14.

In geometry, an arc is a curved portion of a circle. It is defined by two endpoints and the points along the circumference of the circle that lie between the endpoints. The measure of an arc is typically given in degrees.

The measure around a circle is called a circumference, rather than a perimeter. The term "perimeter" is used for polygons. The circumference of a circle is equal to the diameter, multiplied by pi - or to the radius, multiplied by 2 x pi. The number pi - which can be defined precisely as the ratio between the circumference and the diameter of a circle - is approximately 3.1416.

I presume you mean the circumference of a circle. If P and Q are two points on the circumference of a circle with center O, the number of degrees in the arc PQ is defined as the number of degrees in the angle POQ.

Pi is defined as the circumference of a circle divided by its diameter. This relationship carries a value of approximately 3.14159 as a constant. Additionally, Pi is defined also by a circle's area divided by its radius squared.

The circumference is not always 3.14 , The circumference of a circle is always (pi) times as long as the circle's diameter. (Pi) is a number that can't be exactly written down with digits, that begins with 3.14 . It's defined as the ratio of any circle's circumference to the same circle's diameter. The reason is because that's one of the properties of the thing that we call a "circle".
