- 1.A circle has circumference 31.4 cm. Using π = 3.14, work out the radius of the circle.
- 2.Two circles are drawn with the same centre but different radii. Write down the term used to describe this pair of circles.
- 3.A chord is drawn across a circle, dividing the circle into two regions. Write down the name of one of these two regions.
- 4.The curved part of a circle's circumference, between two points on the circle, has its own name. Write down this name.
- 5.Write down the term for the distance all the way around the edge of a circle.
- 6.A circle has centre O. PQ, RS and TU are three chords of the circle, and only one of them passes through O. Write down what this tells you about that chord.
- 7.A cyclist rides around a perfectly circular track with centre O. At every moment of the ride, the distance from O to the cyclist is exactly the same. Which term names this fixed distance?
- 8.A chord divides a circle into two regions, one larger than the other. Write down the term used for the smaller of these two regions.
- 9.A sector of a circle is bounded by two straight edges and one curved edge. Write down the mathematical term for each of the two straight edges.
- 10.A circle has a radius of 3 cm. Work out the diameter of the circle.
- 11.A trundle wheel has a diameter of 0.5 m. It is rolled along the ground and makes 20 complete turns. Using π = 3.14, work out the total distance rolled, in metres.
- 12.Every point on a circle is exactly the same distance from one particular point. Write down the name of that point.
- 13.A diameter divides a circle into two equal halves. Write down the special name given to each of these two halves.
- 14.Two points on a circle divide its circumference into two arcs of different lengths. Write down the name given to the shorter of the two arcs.
- 15.A circle has diameter 10 cm. Using π = 3.14, work out the circumference of the circle.
