1.	In the diagram above, RS is the diameter of the circle. Find the value of .
2.	In the diagram above, O is the centre of the circle and POR is the diameter of the circle. Find the value of .
3.	In the diagram above PQRS is a square. PTQ, QUR, and RVS are equilateral triangles. Find the perimeter of the whole diagram.
4.	In the diagram above, PQRSTU is a regular hexagon. QABR is a square. Find the perimeter of the whole diagram.
5.	In the diagram above, VQ = QS. Calculate the area of the shaded region in cm 2. 6. Given that 6 – 2m = 2 – 8m, then m = 7. Given that 6m + 4 = 2 ( 3 – m), then m =   8. Given that 2m – 5(1 – m) = 9, then m = 9. Given that 4m – 3n = 18 and 4m + n = 10, then m = 10. Given that m – 3n = 7 and 2m = n –1, then n =
