1. A regular octagon has an area of 500 cm squared. How long to the nearest centimetre is one side of the octagon?
2. Ricky is on an island looking for some treasure. He starts at point X by the palm tree and walks 150m in a direction of 230 degrees north to point Y. He then walks 80m in a direction of 140 degrees north to point Z. At point Z he digs and finds the treasure.
How far in metres is point Z from point X?
(I added the colour to make it more visually exciting, though it may not be.)

3. A water cooler has cone-shaped paper drinking cups. The volume of a cone can be found using this formula: V = (Pi x radius squared x height) divided by 3
Anton pours water into a cup until it contains water to half of its volume.
What is the depth of the water, to the nearest millimetre, in the cup?

4. A car follows another car along a straight stretch of an open highway at 100 kilometres per hour. The cars are 150m apart. The cars approach a town. When each car reaches the town it slows down at the same rate to 30 kilometres per hour. Both cars travel through the town at 30 kilometres per hour.
How far apart will the cars be when they are both travelling at 30 kilometres per hour?
