The Circumference (C) of a circle will ALWAYS be 3.1415926 times its Diameter (D).
This irrational number (which goes on forever) is called "pi".
C = pi x D
This will work for any circle, because as the circle gets bigger or smaller, so does the circumference by the same scale.

If the diameter of the circle is 69mm then what is the circumference of this circle?
To find the circumference of a circle, you can use the formula C = πd, where C is the circumference, π is a constant approximately equal to 3.14159, and d is the diameter of the circle. Given that the diameter of the circle is 69mm, you can substitute this value into the formula: C = π * 69mm ≈ 216.769mm. Therefore, the circumference of the circle is approximately 216.769mm.
If a circle has a diameter of 19 what is th circumference?
If a circle has a diameter of 19, the circumference is: 59.7 (diameter x Pi = circumference)
What is the circumference of a circle if the diameter is 12cm?
The circumference of a circle if the diameter is 12cm is 37.7cm
What is the circumference of a circle with an diameter of 6cm?
The circumference of a circle with a diameter of 6cm is about 18.85cm
What is the circumference of a circle 14' in diameter?
The circumference of a circle 14' in diameter is about 43.98'
What is the ratio of the circumference and diameter of a circle?
The circumference of a circle divided by its diameter is a constant referred to as Pi, and is roughly equal to 3.14156.
Why the formula of circumference of circle always constant?
Because:- circumference/diameter = pi and when the formula is rearranged circumference = pi*diameter
How is pi related to the diameter of a circle?
Pi is related to the diameter of a circle through the circumference. C=(pi)*d C = circumference (perimeter of the circle) pi = constant d = diameter
What happens to the circumference of a circle if you double the diameter?
As circumference = π x diameter and π is constant (≈ 3.14159), doubling the diameter will double the circumference.
Why the value of pi is constant?
The value of pi is constant. It is calculated by dividing the circumference of a circle by its diameter. As the circle's circumference grows, the diameter grows at the same rate, proportionally. This means that the circumference divided by the diameter (if measured precisely) will always yield pi. If it does not, it is not a perfect circle. The ratio between the circumference and the diameter of a circle will always stay the same, no matter how you change the size of the circle.
What is the mathematical relationship between the circumference of a circle and its diameter?
The circumference of a circle when divided by its diameter is the value of pi which is an irrational number.
What is the diameter of a circle with the circumference of three feet?
The ratio between the diameter of a circle and its circumference is constant: π. A circle whose circumference measures 3 feet has a diameter of 3/π feet: approximately 11.459 inches.
If the diameter of the circle is 69mm then what is the circumference of this circle?
To find the circumference of a circle, you can use the formula C = πd, where C is the circumference, π is a constant approximately equal to 3.14159, and d is the diameter of the circle. Given that the diameter of the circle is 69mm, you can substitute this value into the formula: C = π * 69mm ≈ 216.769mm. Therefore, the circumference of the circle is approximately 216.769mm.
What is the circumference of 44' diameter?
circumference of any circle = pi (a constant) * diameter = 3.14159 * diameter,so 3.14159 * 44' = 138.23'
How do you find the circumference of a circle using the length of the diameter?
Multiply the diameter by the constant pi.
What are two quantities whose ratio is constant?
The diameter and circumference of a circle.
Starting with the diameter how do you get to the circumference of a circle?
The circumference = Pi x the diameter. Pi is the constant number 3.1416. C = 3.1416D. Multiply the diameter by 3.1416.
