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 = circumference
Pi is approximately 3.14159265358979323846...

circumference = pi*diameter or pi = circumference/diameter
Because the circumference of any circle divided by its diameter is always equal to pi.
Circumfrence = pi * diameter It can be experimentally derived very easily.
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.
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
circumference = pi*diameter or pi = circumference/diameter
The circumference is pi times the diameter.
Yes because: circumference/diameter = pi and circumference = pi*diameter
Circumference = diameter x pi
Circumference of a circle is approximately 3.1416 times the diameter of the circle.
Circumference = 2*pi*Radius Diameter = 2*Radius Circumference = pi*Diameter
pi
Because the circumference of any circle divided by its diameter is always equal to pi.
What is the relationship between the circumference and the diameter? Answer The circumference divided by pi gives the diameter. d = C / pi An alternate way to express the above answer. For all circles, pi is the ratio of the circumference to the diameter pi = C / d
pi X diameter = circumference of the circle.
The circumference and diameter
The mathematical relationship between the circumference of a circle and its diameter is given by the formula C = π * d, where C represents the circumference, d represents the diameter, and π is a constant approximately equal to 3.14159. This formula shows that the circumference is equal to π times the diameter of the circle. This relationship is fundamental in geometry and is used to calculate the circumference of a circle when the diameter is known.
