Introduction of arc length

Introduction of arc length:

Arc length formula: arc length S = (2r )( 1/360 ) degrees

Here An arc is a segment which is closed, of a differentiable curve in the two-dimensional plane; for example, a circular arc is a segment of the circumference of a circle.And If the arc segment occupies a greater circle (or great ellipse), it is considered a great-arc segment.

An arc length of a circle(with radius r) and subtending an angle [theta] (measured in radians) with the circle center — i.e., the central angle — equals [theta] r.

Arc Length Circle Formula:
Arc length circle formula in degree:
arc length S = (2r )( 1/360 ) degrees
Where, (theta) is represented by the angle of opposed the arc of circle. = 3.142 (approximately). Radius of the circle is denoted by r.
Arc length circle formula in radians:
Arc length S = r (theta) radians
circle radius is denoted by r, and is represented by origin angle of the circle.
