Answer The length around a circle has a special name called circumference. Circumference = pi times diameter
The circumference is the distance around a closed curve. Circumference is a kind of perimeter.
The circumference of a circle can be calculated from its diameter using the formula:
C = pi times d
Or, substituting the diameter for the radius:
C = 2 r times pi
where r is the radius and d is the diameter of the circle, and π (the Greek letter pi).

How can you illustrate the definition of a circle?
A circle is a shape with a circumference of 360 degrees.
What is a definition for a 180 degree edge of a circle?
It is an arc comprising half the circumference.
What is the definition for degree of an angle?
one three-hundred-and-sixtieth of the circumference of a circle
What happens to the circumference of a circle if you triple the radius?
Since circumference is proportional to the diameter (the proportionality is the definition of the irrational number pi) and the radius is just twice the diameter, if you triple the radius, you also triple the circumference.
What is the circumference of a circle with a diameter of 1 inch?
You need the formula circumference = pi x diameter pi = 3.14.. This is by the way the definition of the special number pi.
What definition of circumference?
The circumference is the distance around a closed curve. Circumference is a special perimeter.
What is the definition of girth?
The distance around something; the circumference.
What is the circumference of a circle with a 25ft 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.
What is the definition of the word arc?
An arc is part of the circumference of a circle

What is the definition of cercumference and radius of pi.?
Circumference is the enclosing boundary of a curved geometric figure, especially a circle. Radius is a straight line from the center to the circumference of a circle or sphere. Pi is the numerical value of the ratio of the circumference of a circle to its diameter and does not have a circumference or radius of its own.
