40%
Correct answer:
20%
Explanation:
The arc length of a sector, in degrees, is equal to the central angle. The total number of a degrees of a circle is 360. Therefore, we can use a proportion to calculate the percentage.
72360=x100
7200=360x
20=x
Therefore, 20% of the circle is comprised of the sector.
