- 1.A circle has a diameter of 4 cm. Work out the radius of the circle.
- 2.A chord is drawn across a circle, dividing the circle into two regions. Write down the name of one of these two regions.
- 3.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.
- 4.The curved part of a circle's circumference, between two points on the circle, has its own name. Write down this name.
- 5.Every point on a circle is exactly the same distance from one particular point. Write down the name of that point.
- 6.A circle has a radius of 3 cm. Work out the diameter of the circle.
- 7.In one circle, chord PQ is 6 cm long, chord RS is 10 cm long, chord TU is 14 cm long and chord VW is 15 cm long. Write down which of these chords lies closest to the centre of the circle.
- 8.A chord divides a circle into two segments of different sizes. Write down the name given to the smaller of the two segments.
- 9.A circle has circumference 31.4 cm. Using π = 3.14, work out the radius of the circle.
- 10.A circle has two straight radii drawn from the centre to the edge, together with the arc between them. Write down the name of the region enclosed by these two radii and the arc.
- 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 diameter of a circle is an example of a more general type of straight line joining two points on the circle. Which term names that more general type of line?
- 13.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?
- 14.Two circles are drawn with the same centre but different radii. Write down the term used to describe this pair of circles.
- 15.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.
