The distance around the circle is a circumference. The distance across the circle is the diameter (d). The radius (r) is the distance from the center to a point on the circle. (Pi = 3.14) More aboutcircles.

What else can I help you with?
Why is finding the perimeter of a triangle related to finding the perimeter of a rectangle?
It is not in all but a trivial sense - that they are both to do with finding the perimeter!
What is the use of perimeter?
Find the length of the sides of the object. Good for finding how much fencing you would need to enclose an area.
What is the perimeter of 8?
the perimeter means the length around an object. so your perimeter around the object you have must be 8.
What is the difference between finding the perimeter of a polygon and finding the area of a polygon?
Finding the perimeter of a polygon is finding how far it is in total along all the edges of the polygon; whereas finding the area of a polygon is finding how much space the polygon covers. The perimeter of a polygon forms the boundary around the area of the polygon.
What is perimeter in geometry?
in geometry, perimeter is the length around the outside of an object.

How do you solve perimeter of a triangle?
You find the perimeter of a triangle by adding all the sides. There is no special rule for finding the perimeter.
When finding the perimeter do you add?
Yes, for the perimeter of a polygon, you add up all the sides.
What is perimeter in geometry?
in geometry, perimeter is the length around the outside of an object.
What is the perimeter of a 12 by 13 by 5?
The perimeter is a characteristic of a 2-dimensional object. A 12 by 13 by 5 sounds like a 3-dimensional object which would not have a perimeter.
Are the units for finding perimeter always square?
No, perimeter is always measured in units of length (L)
What is the formula for finding perimeter of a rhombus?
Perimeter = 4*n whereas n is the length of its side
