5. The area of a circle is 24 cm2.
Calculate the radius of the circle. [3]
| Scheme | Marks | Comments |
|---|---|---|
| \(\pi \times r^2 = 24\) | M1 | |
| \(r^2 = 24 \div \pi\) | A1 | This implies M1 |
| \(r = 2.76(3\ldots\) cm) | A1 | Accept \(r = 2.8\)(cm) or from correct working \(r = 3\)(cm) If no marks, award SC1 for an answer of 2.77 (cm) |
