Higher November 2017 Paper 1 Q7
7 Here is a quarter circle of radius 6 cm
Not drawn accurately
Work out the area of the quarter circle.
Give your answer in terms of \(\pi\). [2 marks]
| Answer | Mark | Comments |
|---|---|---|
| \(\pi \times 6 \times 6\) or \(36\pi\) or [113, 113.112] or \(9 \times [3.14, 3.142]\) or [28.26, 28.3] | M1 | oe accept [3.14, 3.142] for \(\pi\) |
| \(9\pi\) or \(9 \times \pi\) or \(\pi 9\) or \(\pi \times 9\) | A1 |
Additional guidance
| \(36\pi\) followed by an incorrect method eg \(36\pi \div 2 = 18\pi\) with answer \(18\pi\) | M1A0 |
| Answer of \(9\pi\) from \(\pi \times 3^2\) | M0A0 |
| \(9\pi\) and [28.26, 28.3] given on answer line | M1A0 |
| \(\pi r^2\) stated but followed by 36 or 9 | M0A0 |
