5 The diagram shows a sector \(AOB\) of a circle with centre \(O\) and radius 8 cm.
The angle \(AOB\) is 1.4 radians.
Find the area of the sector. [2 marks]
| Scheme | Marks | AO |
|---|---|---|
| Recalls the formula for the area of a sector \(A = \dfrac{1}{2}r^2\theta\) Or Recalls \(A = \dfrac{\theta}{360}\pi r^2\) and changes their angle to AWRT \(80.2^\circ\) | M1 | 1.2 |
| Obtains \(\dfrac{224}{5}\) OE Condone missing or incorrect units If units are converted the value must be correct. | A1 | 1.1b |
