Circumfrence = pi * diameter
It can be experimentally derived very easily.
Because the circumference of any circle divided by its diameter is always equal to pi.
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.
The distance across a circle through the center is called the diameter. The distance around a circle is called the circumference. Pi is the ratio of the circumference of a circle to the diameter. So,2 radius x Pi = circumferencePi is approximately 3.14159265358979323846...
81.2m (approx). 'Pi' (approx 3.142 ) is the quantity that expresses the relationship between the diameter of a circle and its circumference. ie. the circumference is 3.142 times greater than the diameter. To solve your problem, divide 255 metres by 3.142
If the diameter of a circle is 69mm then the circumference is: 216.8mm (diameter x pi = circumference).
Circumference of a circle is approximately 3.1416 times the diameter of the circle.
The circumference is pi times the diameter.
Yes because: circumference/diameter = pi and circumference = pi*diameter
Circumference = diameter x pi
pi
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.
diameter times pi(3.14159) equals cicumference
The circumference and diameter
pi X diameter = circumference of the circle.
The circumference of a circle when divided by its diameter is the value of pi which is an irrational number.
Because the circumference of any circle divided by its diameter is always equal to pi.
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.
