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 else can I help you with?
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.
How many degrees is a major arc?
A major arc is defined as an arc of a circle that measures more than 180 degrees but less than 360 degrees. It is the larger of the two arcs created by two endpoints on the circumference of the circle. The exact measurement of a major arc can vary depending on the specific positions of its endpoints.
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
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.
The arc on a circle is 78 degrees the radius is 14 how large is the arc?
The arc is: 19.06 units
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).
How many thousands are in an arc minute?
An arc minute is a unit of angular measurement equal to 1/60th of a degree. Since there are 360 degrees in a full circle, this means there are 21,600 arc minutes in a full circle (360 degrees x 60 arc minutes per degree). Therefore, there are 21.6 thousands in an arc minute.
What arc is exactly 180 degrees?
a semi-circle
