Circumference of a circle?
Boundry of circle is called circumference.
Find the ratio of the circumference to the diameter for each circle 3?
For any circle in a plane, the ratio of circumference to diameter is a number called pi, approximately 3.14.
What is a irrational number equal to the circumference to the diameter of the circle?
The circumference of a circle divided by its diameter is equal to pi which is an irrational number.
What is the circumference of a circle if the diameter is Cm?
To get the circumference, multiply the diameter by the number pi.
Why is the ratio of the circumference and diameter of a circle an irrational number?
Because the circumference of a circle divided by its diameter is equal to pi which is an irrational number.
What is the circumference of a circle if the diameter is 18 feet?
The circumference of a circle is determined by multiplying the diameter (d) by the number pi. Therefore, the circumference of a circle with a diameter (d) of 18 feet is 18pi or 18x3.14159265358979323846... Roughly 56.54866776461627829228.
Is the circumference of a circle considered to be a whole number?
No because the circumference of a circle is pi times diameter and pi is an irrational number
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 pi in an explanatory form not the number form?
pi is the ratio between the circumference of a circle and it's diameter. If you take the circumference of any circle, and divide it by that same circle's diameter, the resulting number will be pi.
Is the circumference of a circle to the diameter constant?
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 is the circumference of a circle if the diameter is 57mm?
Circumference of circle: 57*pi = 179 mm to the nearest whole number
What is the formula to find diameter of circle when the circumference is known?
The number pi can be defined as: pi = circumference / diameter. Solving for diameter: diameter = circumference / pi. Pi is approximately 3.14.
