Circumference is the distance around an object. Most usually applied to a circle,
but any closed figure, building, octagon, etc, all have a circumference. Even a
non-regular object such as a tree or a meteor crater has a circumference. The
units used are entirely up to the measurer. Whether Imperial, SI, or whatever
you like, a circumference is always described in a unit of length.
No. "pi" is the 'ratio' of circumference to diameter of a circle. It doesn't care what the unit is,just as long as both are measured in the same unit.
The unit for a circumference is the same as the unit for length (or radius or diameter).
Since the radius of the unit circle is 1, the circumference is 2 x pi.
Diameter.
The circumference of the Earth measured between the North and South poles is approximately 40,007.86 kilometers.
The circumference is the distance around a circle and it is measured by:- Circumference of a circle = 2*pi*radius or pi*diameter
It is used in finding the circumference and area of a circle. Circumference = 2*pi*radius or pi*diameter measured in linear units Area = pi*radius2 measured in square units
The circumference is 27.646 units.
== == Given that the circumference of the earth is 40,075.02 km (measured at the equator) the circumference in inches is roughly 1,577,756,664 inches.
