The circumference of a circle divided by its radius equals 2π. This is a fundamental constant in mathematics known as tau (τ), which is approximately 6.283. The ratio of the circumference to the radius is consistent for all circles, making it a key relationship in geometry and trigonometry. This relationship is crucial for calculating various properties of circles and circular motion.

Is the radius of a circle divided by the circumference of a circle pi?
No, the circumference of the circle divided by the diameter is pi.
What is the diameter and radius of the circumference 16.956?
The diameter is (the circumference) divided by (pi) . The radius is 1/2 of the diameter.
What does a 300 m circumference equal what radius?
Half the diameter is the radius. Circumference = 300 m gives radius = 47.75 metres (to 2 dp).
What is the radius of a circle if the circumference is 244.92?
Circumf. divided by 2Pi = radius 244.92 / 2Pi = 38.98 radius (to nearest hundredth).
What is the circumference of a circle if the radius is 3.5 yards?
The circumference of a circle is equal to 2 x pi x radius, where "pi" is approximately 3.1416.
How much does a diameter equal to?
twice the radius or circumference divided by pie
The radius is about what to the circumference?
The radius is the circumference divided by pie, all divided by two. :)
What is the relationship between the radius of a circle and the circumference?
any circles circumference divided by its diameter will equal pi, or 3.14159 approximately
What is the radius of a circle whose circumference is 36 pi?
The radius of a circle whose circumference is 36 pi (113.1) is: 18 (circumference divided by Pi divided by 2 = radius)
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.
What is the equation for determining radius of a circle if you have the circumference?
Circumference = Diameter multiplied by Pi Diameter = Circumference divided by pi Radius = Diameter divided by 2.
What is the radius if you have the circumference?
Circumference divided by pi to find the diameter then divide that by 2 to give you the radius.
How do you find out the radious of a circle?
The radius of a circle is the distance from the centre of the circle to a point on the circumference of the circle. If it is a drawing and the circle is to scale the radius can be measured with a ruler. If not, the radius can be calculated if the diameter, circumference or area of the circle is known. the radius is equal to: - the diameter divided by 2 - the circumference divided by 2pi(approx. 6.284) - the square root of the area divided pi (divide by pi first, then take the square root)
What is the radius of a sphere?
A radius of a sphere is the distance from its centre to its surface. It is also half of the diameter. If you know the circumference of a circle, you can calculate its radius. Circumference divided by Pi divided by 2 = radius.
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
Is the radius of a circle divided by the circumference of a circle pi?
No, the circumference of the circle divided by the diameter is pi.
What is the diameter and radius of the circumference 16.956?
The diameter is (the circumference) divided by (pi) . The radius is 1/2 of the diameter.
