The length of an arc of a circle is obtained by using the formula L=?r?/180, where L is the length of the minor arc of the circle, r is the radius of the circle and ? is the angle ...

Definition of arc length and formula to calculate it from the radius and central

All you have to do is take any angle you get -- say, 60 degrees -- and you want to find out how many radians that is, just multiply it by the conversion factor: Sixty degrees times pi radians is 180 degrees. If I want to find how far this car travels as it travels aro... More »
Arc of a Circle. A connected section of the circumference of a circle. Arcs are
measured in two ways: as the measure of the central angle, or as the length of
In a circle, the length of an arc is a portion of the circumference. Remembering
that the arc measure is the measure of the central angle, a definition can be ...
(The arc length discussed on this page will be in relation to a circle.) An arc of a
circle is a "portion" of the circumference of the circle. The length of an arc is ...
An angle's measurement in radians is numerically equal to the length of a
corresponding arc of a unit circle. The unit was formerly an SI supplementary unit,
Now the circumference of a circle is an arc length. And the ratio of the
circumference to the diameter is the basis of radian measure. That ratio is the
definition of ...
