- 1.A circle has diameter 10 cm. Using π = 3.14, work out the circumference of the circle.
- 2.Every point on a circle is exactly the same distance from one particular point. Write down the name of that point.
- 3.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.
- 4.A sector of a circle has an angle of 90° at the centre. Write down what fraction of the whole circle this sector represents.
- 5.A tangent touches a circle with centre O at the point P. Q is a point on the tangent. Write down the circle fact that tells you the size of angle OPQ.
- 6.A diameter divides a circle into two equal halves. Write down the special name given to each of these two halves.
- 7.A circle has circumference 31.4 cm. Using π = 3.14, work out the radius of the circle.
- 8.A circle has a diameter of 4 cm. Work out the radius of the circle.
- 9.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.
- 10.A straight line is drawn from the centre of a circle to a point on the circle. Write down the name of this line.
- 11.A tangent to a circle touches the circle at exactly one point, P. Work out the size of the angle between the tangent and the radius drawn to P.
- 12.A circle has a radius of 3 cm. Work out the diameter of the circle.
- 13.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.
- 14.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.
- 15.A circle is drawn on a page. Write down how many radii can be drawn in the circle.
