A circle consists of 360°So, for example, if the department's budget were
1/4 of the company’s total annual budget, then the central angle of the sector representing the department would be 90° (since
1/4 of
360° = 90°)
Likewise, if the department's budget is
5/18 of the company’s total annual budget, then the central angle of the sector representing the department =
5/18 of
360° = 100°
Answer: D
