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.
What else can I help you with?
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 the diameter of a circle is 9 what is the circumference?
If the diameter of a circle is 9 the circumference is: 28.3
If a circle has a diameter of 5 what is the circumference?
If a circle has a diameter of 5 the circumference is: 31.4
Circumference of a circle with a diameter of 51m?
The circumference of a circle with a diameter of 51m is: 160m
If a circle has the diameter of 2.25 what is the circumference?
If a circle has a diameter of 2.25, the circumference is: 7.069
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
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.
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
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.
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'
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.
What is the mathematical relationship between the circumference of a circle and its 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.
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.
