- 1.A straight line is drawn from the centre of a circle to a point on the circle. Write down the name of this line.
- 2.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.
- 3.Write down the term for the distance all the way around the edge of a circle.
- 4.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.
- 5.A circle has diameter 10 cm. Using π = 3.14, work out the circumference of the circle.
- 6.A circle is drawn on a page. Write down how many radii can be drawn in the circle.
- 7.A chord is drawn across a circle, dividing the circle into two regions. Write down the name of one of these two regions.
- 8.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?
- 9.A tangent to a circle with centre O touches the circle at point P, where OP = 5 cm. Point Q lies on the tangent so that PQ = 12 cm. Using the fact that a tangent is perpendicular to the radius at the point of contact, work out the length OQ.
- 10.A circle has a diameter of 4 cm. Work out the radius of the circle.
- 11.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.
- 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 diameter divides a circle into two equal halves. Write down the special name given to each of these two halves.
- 14.The curved part of a circle's circumference, between two points on the circle, has its own name. Write down this name.
- 15.Two circles are drawn with the same centre but different radii. Write down the term used to describe this pair of circles.
