Illustration of a unit circle. The variable t is an angle measure. Animation of the act of unrolling the circumference of a unit circle, a circle with radius of 1. Since C = 2πr, the circumference of a unit circle is 2π. In mathematics, a unit circle is a circle of unit radius—that is, a radius of 1. [1]
The unit of measurement varies by region: a United States liquid tablespoon is approximately 14.8 ml (0.50 US fl oz), a European, United Kingdom and Canadian tablespoon is exactly 15 ml (0.51 US fl oz), [2] and an Australian tablespoon is 20 ml (0.68 US fl oz). [3]
These cutlery spoons are also called a "teaspoon" and "tablespoon", but are not necessarily the same volume as measuring spoons with the same names: Cutlery spoons are not made to standard sizes and may hold 2.5~7.3 ml (50%~146% of 5 ml) for teaspoons [3] and 7~20 ml (47%~133% of 15 ml) for tablespoons. The difference in size can be dangerous ...

where C is the circumference of a circle, d is the diameter, and r is the radius. More generally, = where L and w are, respectively, the perimeter and the width of any curve of constant width. = where A is the area of a circle. More generally, =
A page from Archimedes' Measurement of a Circle. Measurement of a Circle or Dimension of the Circle (Greek: Κύκλου μέτρησις, Kuklou metrēsis) [1] is a treatise that consists of three propositions, probably made by Archimedes, ca. 250 BCE. [2] [3] The treatise is only a fraction of what was a longer work. [4] [5]
The circumference of a circle is the distance around it, but if, as in many elementary treatments, distance is defined in terms of straight lines, this cannot be used as a definition. Under these circumstances, the circumference of a circle may be defined as the limit of the perimeters of inscribed regular polygons as the number of sides ...
