You must show all your working. [4]
| Scheme | Marks | Comments |
|---|---|---|
| (radius = ) \(\dfrac{40.841}{2\pi}\) (= 6.50…) | B2 | B1 for \(2\pi r = 40.841\) or \(\pi d = 40.841\) or \(\frac{40.841}{\pi}\) or 13.0 |
| (Area = ) \(\pi \times \left(\dfrac{40.841}{2\pi}\right)^2\) (\(= \pi \times 6.5^2\)) | M1 | FT ‘their derived radius’ |
| 132.7(…) or 133 (cm\(^2\)) | A1 | CAO correct answer implies all previous marks |
