| Answer | Mark | Comments |
|---|---|---|
| \(0.5 \times 2.6 \times 9.8\) | M1 | oe eg \(1.3 \times 9.8\) or \(2.6 \times 4.9\) |
| 12.7(4) | A1 |
Additional guidance
| Accept 13 with M1 awarded | M1A1 |
| Answer | Mark | Comments |
|---|---|---|
| \(\pi \times 11.5^2\) | M1 | oe accept [3.14, 3.142] for \(\pi\) |
| [415, 416] or \(\dfrac{529}{4}\pi\) or \(132.25\pi\) | A1 | oe |
Additional guidance
| Accept \(\dfrac{529}{4} \times \pi\) or \(132.25 \times \pi\) or \(\pi \times \dfrac{529}{4}\) or \(\pi \times 132.25\) | M1A1 |
| Condone \(\pi\dfrac{529}{4}\) or \(\pi 132.25\) | M1A1 |
