the radius
2 x pi x r where pi = 3.1416
To find the perimeter you do pi (3.1415) times the diameter.
Or you can figure by the radius (P=2 π r; i.e. Perimeter = 2 x 3.1415 x radius)
The perimeter of a circle is its circumference. We use these formulas to find the circumference of a circle; C=d times pi or C=2 times the radius times pi (3.14).
To make it easier to explain:
Area: Pi (3.14) X Radius Squared (r 2) from the center out of the circle
Perimeter: Pi (3.14) X Diameter (d) from one side of the circle to the other
The perimeter of a circle is called Circumfrence.
Here is the formula for Circumfrence:
C= pi x d (pi times diameter)
C= 3.14 x ______ (fill in the blank with the diameter of the circle)
C= (your answer)
NOTE: Pi is equal to 3.14 so when you are using pi to multiply, replace it with 3.14
When the diameter is not given in a circle, double the radius to find the length of the diameter.
The perimeter of a circle is its circumference
The perimeter of a circle is its circumference
The perimeter of a circle is its circumference
The perimeter of a circle would be the circumference.
The circumference of a circle is the length of the circle's perimeter.
When the shape is a circle, then the perimeter is called"circumference".The circumference IS the perimeter of a circle.
The length of the perimeter is the circumference. The perimeter itself is the boundary between the interior and exterior of the circle. The perimeter of a circle is called the circumference
The perimeter of a circle is its circumference
No because the perimeter of a circle is its circumference

The perimeter of a circle would be the circumference.
The perimeter of a circle is its circumference
Pi (3.1415...) times the diameter of the circle = the perimeter
Circumference ("perimeter") of a circle = (pi) x (diameter of the circle)
The circumference of a circle is the length of the circle's perimeter.
When the shape is a circle, then the perimeter is called"circumference".The circumference IS the perimeter of a circle.
The length of the perimeter is the circumference. The perimeter itself is the boundary between the interior and exterior of the circle. The perimeter of a circle is called the circumference
The perimeter is also known as the circumference of a circle.
The perimeter of a circle is the same as its circumference!
