The circumference of a circle is NOT 360 degrees. The circumference is the distance around the curve of the circle. This has a measurement unit of length, not degrees. The angular displacement, in going completely around any point is 360 degrees and that follows from the definition of a degree.

∙ 8y agoIt has been DEFINED that way, many centuries ago. You can divide the circle into as many parts as you want, but in the past, people seemed to like multiples of 12.A much more natural unit for angles is the radian. In that case, the circumference is equal to 2 x pi. It turns out that many formulae are simpler when angles are expressed in radians.

How many degrees in a circle?
360 degrees are in a circle no matter how big or small the circle is A circle has 360 degrees.
How do you find the length of the arc of a circle with only the measurement of the central angle and the Circumference?
The entire circumference has a central angle of 360 degrees. The arc is a fraction of the circumference. The fraction is (central angle) divided by (360). So the arc length is: (circumference) x (central angle) / (360) .
Why is a revolution 360 degrees?
There are 360 degrees in a circle and a revolution is when something turns in a circle. There are aslo 360 degrees around a point.
What is the fraction of 20 degrees?
20 degrees is 20/360 = 1/18 of a circle.20 degrees is 20/360 = 1/18 of a circle.20 degrees is 20/360 = 1/18 of a circle.20 degrees is 20/360 = 1/18 of a circle.
What is the radius of a circle in which a 30 degrees arc is 2 inches long?
360/30*2 = 24 = circumference of the circle 24/2*pi = 3.819718634 inches = radius of the circle
How many degrees is the circumference of a circle?
360 degrees
What you called a circle has 360 of these units?
A circle's circumference has 360 degrees around it.
If a 120 degree arc is 12mm long what is the circumference of the whole circle?
360 degrees in a circle 120 degrees = 12mm 360 degrees = 36mm Therefore the circumference of the circle is 36mm.
What is 90 degrees of a circle?
The circumference of a circle is 360 degrees. 1/4 of 360 is 90. So 90 degrees is a quarter of a circle. It is called a quadrant.
How can you illustrate the definition of a circle?
A circle is a shape with a circumference of 360 degrees.
Distance around a circle?
360 degrees - Circumference A+
What is the circumference of a circle whose arc length is 19.68 and degrees is 94?
The circumference will have 360 degrees. So the arc is 94/360 of the whole circle. That is, the whole circle will be 360/94 of the arc length. So the circumference of the shole circle is 19.68*360/94 = 75.37 units (to 2 dp)
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.
What part of the circle does 1 degree represent?
It will represent 1/360 of a circle's circumference of 360 degrees
What is one fourth part of the circle?
It is 90 degrees of the circle's circumference which has a full turn of 360 degrees.
What fraction of a circle is 15 degrees?
It is: 15/360 = 1/24 of a circle's circumference
In detail about edges of a circle?
The edge or perimeter of a circle is its circumference of a full turn of 360 degrees
