You have to remember that the complete circle is 360°.
When they tell you that the sector is some percent of the circle, it's the same percent of 360° !
Example:
A sector is 40 percent of the circle. How many degrees is it ?
40 percent is the same as 0.40
Multiply (0.40 x 360°) and you get 144°. Is that cool ? !

What is the degree measure of 11 percent sector?
The angle of the sector measures 39.6 degrees (.11*360).
What is the degree measure of 50 percent?
50% of what degree. 50% of 360degrees is 180degrees 50% of 180degrees is 90degrees 50% of 90degrees is 45degrees 50% of 260degrees is 130degrees
If the arc length of a sector in the unit circle is 3 radians what is the measure of the angle of the sector?
In a unit circle, the arc length ( s ) is directly equal to the angle ( \theta ) in radians. Therefore, if the arc length of a sector is 3 radians, the measure of the angle of the sector is also 3 radians.
True or fulse To find the area of a sector you multiply the area of the circle by the measure of the arc determined by the sector?
fulse
Is 90 percent used as a label measure count or position?
