Question

If the percentage of the sector is given for example 55% how do you find the central angle?

Answer 1

Answer:

Step-by-step 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.
