Arc AB represents 40/240 = 1/6 of the circumference of the circle.
As the angle at the centre subtended by the whole circle is 360° then ∠A0B (if the center is O) measures 1/6 x 360 = 60°. Since a central angle has the same number of degrees as the arc it intercepts, the arc ACB (note we can call the arc AB as arc ACB) measures 60°.

Does the arc length equals the measure of the arc?
No, in order to fine the arc length you need a formula which is: Circumference x arc measure/360 degrees
What is a measure of an angle as a fractional part of a circle?
An arc is a fraction of its circumference
If the minor arc has a measure of 120 degrees what is the measure of the major arc?
A whole circle is 360 deg so the major arc is 360-120 = 240 degrees.
What is arc in geometry terms?
In geometry, an arc is a curved portion of a circle. It is defined by two endpoints and the points along the circumference of the circle that lie between the endpoints. The measure of an arc is typically given in degrees.
If a circle has radius 6 in and an arc measure of 100 then what is the arc length?
100/360 of the circumference of the circle = 10*pi inches
What is the measure of an arc?

If the arc on a particular circle has an arc length of 12 inches and the circumference of the circle is 48 inches what is the angle measure of the arc?
The angle measure is: 90.01 degrees
What is a measure of an angle as a fractional part of a circle?
An arc is a fraction of its circumference
How do you find the arc length with the angle given?
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.
If the minor arc has a measure of 120 degrees what is the measure of the major arc?
A whole circle is 360 deg so the major arc is 360-120 = 240 degrees.
