Foundation November 2017 Paper 2 Q16
16 A wheel is made of a circular rim and 8 spokes as shown.
Not drawn accurately
The length of each spoke is 37 cm
Work out the total length of the rim and spokes. [3 marks]
| Answer | Mark | Comments |
|---|---|---|
| \(2 \times \pi \times 37\) or \(\pi \times 74\) or \(8 \times 37\) or 296 | M1 | Accept [3.14, 3.142] for \(\pi\) |
| [232, 233] or \(74\pi\) | A1 | May be implied by eg \(74\pi + \ldots\) |
| [528, 529] or \(74\pi + 296\) | A1 |
Additional guidance
| \(360 - 37 \times 8\) | M1A0A0 |
| \(37 \times 8\) or 296 seen and then eg halved or doubled | M1 |
