To find the length of the arc in a circle with a diameter of 8 feet, if the central angle determining it measures 330 degrees, first you need to change the 330 degrees to radians:You need the radius, not the diameter. Half of 8 is 4 , the radius. Now, use that in the formula ...

Segment in a Circle:The area enclosed by the chord and the corresponding arc in a circle is called a segment. There are two types of segments – minor segment, and major segment. Sector of a Circle:The sector of a circle is defined as the area enclosed by two radii and the correspondin...
Arc length formula with degrees: Using the radian formula was faster, since the angle was in radians. 2. Find the arc length in a circle of radius 12 cm with a central angle of 1.2 radians.3. Find the length of the minor arc from point A to point B, when the radius of the circ...
II. Fill in the blanks4 In a circle, if the length of an arc is of the circumference of the circle, then the central angle of the arc is"5 The radius of an arc in a circle is 6 cm and its central angle is 60°. The arc length is cm.6 As shown in the diagram, given t...
Arc Length of a Sector:In mathematics, the arc length of a sector of a circle is the distance along the circle's edge from one point on the edge to another point on the edge. If the angle created between two radii of the circle to two points on t...

Thus the radian measure is based on a ratio -- a number -- that is actually found in a circle. The radian measure is a real number that indicates the ratio of a curved line to a straight, of an arc to the radius. For the ratio of s to r does determine a unique central angle ...
