Work out the area of the circle.
Give your answer in terms of \(\pi\). (3)
| Answer | Mark | Mark scheme |
|---|---|---|
| \(\dfrac{25}{\pi}\) | P1 | for showing \(\pi d = 10\) or \(2\pi r = 10\) or \(r = \dfrac{10}{2\pi}\) or \(d = \dfrac{10}{\pi}\) |
| P1 | (dep P1) for using \(r = \dfrac{5}{\pi}\) or \(r = \dfrac{10}{2\pi}\) or \(d = \dfrac{10}{\pi}\) in \(\pi r^2\) eg \(\pi \times \left(\dfrac{10}{2\pi}\right)^2\) | |
| A1 | oe |
Additional guidance
Need not be simplified but needs to show a single value of \(\pi\)
