Circumference of a circle is approximately 3.1416 times the diameter of the circle.
The circumference is pi times the diameter.
Circumference = diameter x pi
linear. As the diameter of circle increases the circumference of that circle increases. Diameter x pi = Circumference, Diameter x 2 x pi = Circumference x 2.
diameter times pi(3.14159) equals cicumference
The circumference of a circle is equal to pi times its diameter. Another way to say this is that for any circle, circumference divided by diameter will always have pi as the answer, regardless of the size of the circle.
pi X diameter = circumference of the circle.
The circumference and diameter
Because the circumference of any circle divided by its diameter is always equal to pi.
The circumference of a circle when divided by its diameter is the value of pi which is an irrational number.
The circumference is ALL the way around the circle, while the radius is only HALF way into the middle of the circle. I'm guessing you meant "What is the relationship between the radius of a circle and its circumference?" Radius is half of the diameter of a circle, circumference is PI times diameter; therefore, the circumference is PI times two times radius.
