|---|---|---|
| 41.1 | 4 | M1 for method to work out the area of the circle or quarter circle or semi-circle eg \(\pi \times 6^2\) (= 113.(09..)) or \(\pi \times 6^2 \div 2\) (= 56.5(48..)) or \(\pi \times 6^2 \div 4\) (= 28.2(7…)) M1 for method to work out the area of the square eg (= 72) oe or a triangle eg \(\frac{1}{2} \times 6 \times 6\) (= 18) M1 for complete method to find shaded area. A1 for value in the range 41.04 - 41.112 |
