How do you find the measure of a central angle?
You can also use the radius of the circle and the arc length to find the central angle. Call the measure of the central angle θ. Then: θ = s ÷ r, where s is the arc length and r is the radius.

How do you find the central angle in data interpretation?
- In any sector, there are 3 parts to be considered:
- The arc length is a fraction of the circumference. The sector area is a fraction of the whole area. The sector angle is a fraction of 360°
- If the sector is 20% of the pie chart, then each of these parts is 20% of the whole.
How do you find the central angle without arc length?
- Multiply the sector area by 2.
- Then divide the result by the radius squared (the units should be the same) to get the central angle in radians.
- Multiply the central angle by the radius to get the arc length.
