divide the measure of the arc by 360
The fraction of a circle that an arc covers is the angle of the arc divided by 2*pi radians, or divided by 360 degrees if you prefer Imperial Units.
In a circle, the circumference and diameter vary directly. Which of the following equations would allow you to find the diameter of a circle with a circumference of 154 if you know that in a second circle the diameter is 14 when the circumference is 44?
A circle with the radius of 21cm would have an area of approximately 1384.74 cm. You would find this by using the equation of pi*(radius^2) = pi*(21^2).
To find the area of the circle pi*radius*squared and subtract the area of the figure inside
divide the measure of the arc by 360
There are 360 degrees around a circle and if an arc covers 45 degrees of the circle then the fraction is 45/360 or 1/8 in its simplest form
The fraction of a circle that an arc covers is the angle of the arc divided by 2*pi radians, or divided by 360 degrees if you prefer Imperial Units.
That would certainly do it.
the fraction of the circle covered by the arc
To find the fraction of a 360 degree circle that is 30 degrees, you would divide the angle measurement by the total angle of the circle. So, 30 degrees divided by 360 degrees equals 1/12. Therefore, 30 degrees is 1/12 of a 360 degree circle.
To determine the fraction of a circle that 210 degrees represents, we first need to know that a full circle is 360 degrees. Therefore, to find the fraction of the circle represented by 210 degrees, we divide 210 by 360, which equals 0.5833. This can be simplified to 7/12, so 210 degrees represents 7/12 of a circle.
Arctic Circle
There are no reindeer in Antarctica, only in the Arctic. You would be much more likely to find reindeer near the Arctic. It is logically impossible to find a mammal living in the Antarctic Circle. Although reindeer would be able to survive in the Antarctic Circle, they would soon develop hypothermia.

Using a fraction piece with a denominator of 6, we need to find a fraction that, when repeated twice, will cover 4 out of 6 equal parts of a circle. Since 4 out of 6 is equivalent to 2 out of 3, the fraction piece we need is 2/3.
The circumference is 2*pi*radius (not raduis) and this formula is applicable whether the radius is an integer, a fraction, or even an irrational number.
