A circle contains 360 degrees. Draw a circle, add a radius to any point on it, and then rotate the radius completely around. After it has returned to the point it initially intersected the curve, the radius will have rotated through 360 degrees.
(another explanation, maybe no better.)
A complete circle measures 360 degrees, so a half-circle is 180 degrees, a quarter-circle is 90 degrees and so forth. Another way to look at it is in terms of the central angle formed by the radii drawn from each endpoint of the arc - the measure of the arc in degrees is the same as the measure of this central angle in degrees.

How many seconds there are in a circle?
The calculation is 60 arc seconds X 60 arc minutes X 360 degrees in a full circle. So, there are 1,296,000 arc seconds in a full circle.
What is the arc in a circle that is 90 degrees?
To find the arc length, you also need to know the radius (or diameter) of the arc. The arc length is then found by finding the circumference of the full circle (2xPIxradius) and then dividing by 4 to find just one quarter of the circle (90 degrees).
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
How do you find arc of an circle when the degrees is given?
It depends on what measure related to the arc you want to find!
The arc length is 19.68 what is the circumference of the circle?
That depends on the center angle coming from that arc. If it is 90 degrees, multiply the arc by 4, etc.
How many Degrees is 1 arc of the circle?
That will depend on the length of the arc but an arc radian of a circle is about 57.3 degrees
Is a circle an arc?
an arc is a segment of a circle. If the arc subtends a full angle of 360 degrees, then the arc is a circle; but this is a special case of an arc.
What is the number of degrees in an arc of a circle?
It depends on the length of the arc because there are a total of 360 degrees in a complete circle.
What is the circumference of a circle when the arc is 30 degrees and minor arc is 8?
The circumference of a circle is 360 degrees. The circumference of a circle is also 2*pi*radius or diameter*pi.
How do you calculate arc measures?
In degrees because an arc is part of the circumference of a circle which has a total of 360 degrees
The arc on a circle is 78 degrees the radius is 14 how large is the arc?
The arc is: 19.06 units
How many seconds there are in a circle?
The calculation is 60 arc seconds X 60 arc minutes X 360 degrees in a full circle. So, there are 1,296,000 arc seconds in a full circle.
How do you Find x for the arc with 120 degrees and 130 degrees?
The 3rd arc of the circle: 360-120-130 = 110 degrees
What is the arc in a circle that is 90 degrees?
To find the arc length, you also need to know the radius (or diameter) of the arc. The arc length is then found by finding the circumference of the full circle (2xPIxradius) and then dividing by 4 to find just one quarter of the circle (90 degrees).
What arc is exactly 180 degrees?
a semi-circle
How do you draw 2fifths of a circle?
With an arc of 144 degrees
Find the length of the arc on a circle of radius r equals 16 inches intercepted by a central angle 0 theta equals 60 degrees?
The length of an arc on a circle of radius 16, with an arc angle of 60 degrees is about 16.8.The circumference of the circle is 2 pi r, or about 100.5. 60 degrees of a circle is one sixth of the circle, so the arc is one sixth of 100.5, or 16.8.
