The perimeter of a circle is called the circumference
The perimeter of a circle is called the circumference and the formular of finding it is Pi D or 2Pi R
a perimeter is a length of outline of any shape ( but only for circle we call the perimeter as circumference ) .
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.
Its called a perimeter, cause a perimeter is the outside, so it must be a perimeter! :)
In the case of a circle, it is common to call this "circumference" instead of "perimeter". Just multiply the diameter by pi.
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".
A quarter of a circle or a quadrant!
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.
Are you thinking of circumference? That's what one might call the "perimeter" of a circle.
