It 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.
360 degrees are in a circle no matter how big or small the circle is A circle has 360 degrees.
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) .
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.
360/30*2 = 24 = circumference of the circle 24/2*pi = 3.819718634 inches = radius of the 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.20 degrees is 20/360 = 1/18 of a circle.
360 degrees
A circle's circumference has 360 degrees around it.
360 degrees in a circle 120 degrees = 12mm 360 degrees = 36mm Therefore the circumference of the circle is 36mm.
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.
A circle is a shape with a circumference of 360 degrees.
360 degrees - Circumference A+
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)
The circumference of a circle is 360 degrees. The circumference of a circle is also 2*pi*radius or diameter*pi.
It will represent 1/360 of a circle's circumference of 360 degrees
It is 90 degrees of the circle's circumference which has a full turn of 360 degrees.
It is: 15/360 = 1/24 of a circle's circumference
The edge or perimeter of a circle is its circumference of a full turn of 360 degrees
