An arc that measures exactly 180 degrees is called a semicircle. In a circle, a semicircle is formed when an arc spans half of the circumference, which corresponds to 180 degrees. Semicircles are important in geometry and trigonometry, often used in calculations involving angles and circles.
Each arc of the circle will measure 360/5 = 72 degrees
An arc can be measured either in degree or in unit length. An arc is a portion of the circumference of the circle which is determined by the size of its corresponding central angle. We create a proportion that compares the arc to the whole circle first in degree measure and then in unit length. (measure of central angle/360 degrees) = (arc length/circumference) arc length = (measure of central angle/360 degrees)(circumference) But, maybe the angle that determines the arc in your problem is not a central angle. In such a case, find the arc measure in degree, and then write the proportion to find the arc length.
180x2= 360 degrees
If the arc is circular, such a figure is a semicircle or half circle.
A whole circle is 360 deg so the major arc is 360-120 = 240 degrees.
No, in order to fine the arc length you need a formula which is: Circumference x arc measure/360 degrees
Major arc.

(arc length)/circumference=(measure of central angle)/(360 degrees) (arc length)/(2pi*4756)=(45 degrees)/(360 degrees) (arc length)/(9512pi)=45/360 (arc length)=(9512pi)/8 (arc length)=1189pi, which is approximately 3735.3536651

Multiply the radius by 2 and then by 3.14. Divide the length of the arc by this answer. Multiply this fraction by 360 degrees. That will be your answer.
30/360 = one twelfth
