| Topic | Radians, Arc Length and Sector Area |
| Type | Degree-radian conversion |
| Difficulty | Easy -1.8 This is a straightforward conversion using the formula π radians = 180°, requiring only one step of arithmetic (multiply 7/6 by 180). It tests basic recall of the radian-degree relationship with no problem-solving or conceptual depth, making it significantly easier than average A-level questions. |
| Spec | 1.05d Radians: arc length s=r*theta and sector area A=1/2 r^2 theta |
Express $\frac{7\pi}{6}$ radians in degrees. [2]
