An arc is a fraction of its circumference
A protractor can be used to measure an angle. An angle is basically part of a circle. A complete circle is 360 degrees. A right-angle is 90 degrees, half a circle is 180 degrees, and so on.
As in a unit circle, 30 degrees is Pi/3.
60/360 = 1/6th of the whole circle
1 whole circle = 360 degrees2/360 = 1/180 of a circle

6Improved Answer:-There are 360 degrees around a circle and any part of it is an arc.
As in a unit circle, 30 degrees is Pi/3.
60/360 = 1/6th of the whole circle
They are quite similar but a angle isbasically part of the circle. if a had an angle of 90 degrees then it is aquarterof the circle. the circle it the whole thing and the angle is part of the thing
1 whole circle = 360 degrees2/360 = 1/180 of a circle
A litre is a measure of volume. 6 is a pure number. A number cannot be a fractional part of a volume.
A central angle.The section of the circle formed by that angle and the part of the circle (the part being the circumference) between the radii is called a sector.
Part of the circumference of a circle
-- If the fractional part of the angle is less than 1/2 degree, just throw away the fraction and forget about it. -- If the fractional part of the angle is 1/2 degree or more, add one to the degrees and throw away the fraction.

The measure of an arc is part of the circumference of a circle
