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.
