I believe that the distance around a circle is called the circumference.
The distance around a circle is called circumference. Around any other shape, it is called perimeter.
Perimeter is the distance around something. In the case of a circle (or other curved figures), this is simply called the perimeter, so I would say perimeter is the same as circumference. Except that it is uncommon to call the circumference of a circle the "perimeter".
Concentric Circles?
We call it a circle.

The word perimeter means the distance around the outside of an object. The perimeter of a circle has a special name. We call it the circumference. The perimeter of this circle, or circumference, is 25 ft.
It is the circumference.

Its called a perimeter, cause a perimeter is the outside, so it must be a perimeter! :)
The distance of two points of the circle is called as perimeter. Since these two points are located on the same circle, their peripheral distance is measured.
radius
"Circumference" is the distance around the outer edge of a circle. It can be calculated by multiplying the diameter of the circle by pi (approximately 3.14159) or by using the formula 2πr, where r is the radius of the circle.
It's the diameter.
Anything outside your area code is usually long distance.
The distance from a circle to its center (the dot in the middle) is called 'the radius'. The distance from a circle to a point opposite is called 'the diameter'. The diameter is twice the length of the radius.
