How do you calculate the circumference if you know the diameter?
Circumference is equal to 2 times pi (3.1416) times one half of the diameter (the radius). So, if the diameter is 2 cm, then the circumference would be the product of (2) times (3.1416) times (1), or 6.2832 cm. Circumference is equal to diameter times Pi. c = Pi * d diameter times pi
How do you get circumference when you are given radius?
Circumference is equal to pi x diameter Diameter is equal to 2 times the radius Circumference would be 2 x pi x radius
Why is the circumference of a circle diameter times pi or 2 radius times pi?
Because 2 times the radius is equal to the diameter of the circle
Is the radius one fourth of the circumference?
No. It is circumference/(2*pi)No. It is circumference/(2*pi)No. It is circumference/(2*pi)No. It is circumference/(2*pi)
Given the circumference of a circle what is the radius?
Circumference equals the diameter times pi. The diameter is 2 times radius. Radius equals Circumference divided by pi then divided by 2.

How do you get circumference when you are given radius?
Circumference is equal to pi x diameter Diameter is equal to 2 times the radius Circumference would be 2 x pi x radius
Why is the circumference of a circle diameter times pi or 2 radius times pi?
Because 2 times the radius is equal to the diameter of the circle
How do you find the circumference of a circle with just the radius?
The circumference of a circle is equal to the radius times 2*pi. 2*pi*R where R is the radius.
How can circumference equal area?
A=pir2 a=3.14(2)2 a=3.14(4) a=pi*d area =pi r 2 circumference=pi times d in this equation in terms of pi, a=csquared
Radius of 5m what is the circumference?
If you mean a circle: the circumference is equal to diameter x pi, or 2 x pi x radius.If you mean a circle: the circumference is equal to diameter x pi, or 2 x pi x radius.If you mean a circle: the circumference is equal to diameter x pi, or 2 x pi x radius.If you mean a circle: the circumference is equal to diameter x pi, or 2 x pi x radius.
What is the circumference of the can?
Circumference of the can is 2*pi*radius or diameter times pi
What is the circumference if the Diameter equals 3 meters?
Circumference is equal to 2 times pi times the radius. The radius is half the diameter, so pi times the diameter is also the circumference. In this case, the diameter is 3 meters so 3 times pi equals 9.42 So the circumference is about 9.42 meters.
How do you use pi to determine circumference?
Circumference = pi times the diameter, or pi times 2 times radius. Area = pi times (radius squared)
How do you get a circumference?
Using a compass and the circumference is measured by 2 times pi times radius or diameter times pi.
What's is the circumference of the circle if the radius is 10 in?
The circumference of a circle is equal to 2 times pi times the radius of the circle. Therefore, if the radius of the circle is 10 inches, the circumference would be 2 times pi times 10 inches, or 20 pi inches. Pi is a mathematical constant with a value of approximately 3.14, so the circumference of the circle would be approximately 62.8 inches.
In order for the circumference of a circle to equal pie what should the radius be?
It is not pie. That is something you eat. It is pi. Your formula is Circumference = pi times Diameter. Diameter = radius times 2. If you replace Circumference with pi then what do you get? You get pi = pi, or 1 pi = 1 pi. or 1=1. You now know the diameter. if the diameter is 1, what is the radius?
