How many degrees are in the arc of a circle?
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.
What is the sum of the central angles of a circle?
360 degrees
What is the degree measure of a circle?
A circle is 360 degrees if that's what you're asking.
Find the lenght of a chord that cuts off an arc of measure 60 degrees in a circle of radius 12?
The radial length equals the chord length at a central angle of 60 degrees.
What would be the measure of the central angle that you would draw to represent 50 in a circle graph?
The answer will depend on 50 out of how many. If it is 50 out of some number N, then the central angle is 360*50/N degrees.
What is the sum of the central angle measure of a circle?
360 degrees
If a circle is divided into 5 sections by 5 radii and each of the central angles formed are of equal measure what is the measure of each central angle?
72 degrees 72 degrees
What fraction of a circle is a central angle whose measure is 40 degrees?
Nah who needs that!
If a circle was divided into 6 equal parts what would be the degree measure of the central angle?
It is 60 degrees
What is the measure of each central angle of a circle divided into sixth?
It is 360 degrees divided by 6 = 60 degrees each.
If an angle that has a measure of 51.4 degrees is inscribed in a circle what is the measure of its intercepted?
102.8 degrees I think but it depends. If the angle is a central angle it is 51.4 degrees but other than that I think it would be 102.8 degrees.
What is the measure of the central angle of each sector if you divide a circle into five equal sectors?
360 degrees / 5 pieces = 72 degrees
What is defined to be an arc that has an central angle with the measure of 180 degrees?
If the arc is circular, such a figure is a semicircle or half circle.
How do you find the degree measure of a central angle in a circle if both the radius and the length of the intercepted arc are known?
-- Circumference of the circle = (pi) x (radius) -- length of the intercepted arc/circumference = degree measure of the central angle/360 degrees

How do we measure an angle?
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.
How can you find the measure of the central angle with the sector area known?
It is found by: (sector area/entire circle area) times 360 in degrees
