How much of a circle does a 100-degree angle turn through?
A 100-degree angle turns through approximately 27.78% of a circle.
To determine how much of a circle a 100-degree angle turns through, you need to find the angle measure as a fraction of a full circle.
A full circle is 360 degrees, so you can find the fraction by dividing the given angle measure by 360:
100 degrees / 360 degrees = 0.2778
Therefore, a 100-degree angle turns through approximately 0.2778, or about 27.78% of a full circle.
