| Topic | Radians, Arc Length and Sector Area |
| Type | Segment area calculation |
| Difficulty | Moderate -0.3 This is a straightforward application of standard formulas (sector area minus triangle area) with all values given directly. It requires recall of two formulas and basic arithmetic, making it slightly easier than average but not trivial since students must recognize the two-step approach. |
| Spec | 1.05d Radians: arc length s=r*theta and sector area A=1/2 r^2 theta |
