Math Problem Statement
Calculate the size of the central angle of sector B in this pie chart.
Solution
To calculate the size of the central angle of sector B in the pie chart, we can use the following fact:
A full circle has 360 degrees, and sector B is the remaining part of the pie chart after the 140° sector.
- Subtract the angle of the given sector (140°) from 360°:
So, the central angle of sector B is 220°.

Tip: Always remember that the sum of the angles in a circle is 360°, which is useful for calculating missing angles in sectors.
