- 1.A circle has diameter 10 cm. Using π = 3.14, work out the circumference of the circle.
- 2.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.
- 3.A line segment joins two points on the circumference of a circle, without necessarily passing through the centre. Write down the general term for this line segment.
- 4.A circle has a diameter of 4 cm. Work out the radius of the circle.
- 5.Every point on a circle is exactly the same distance from one particular point. Write down the name of that point.
- 6.The curved part of a circle's circumference, between two points on the circle, has its own name. Write down this name.
- 7.Two circles are drawn with the same centre but different radii. Write down the term used to describe this pair of circles.
- 8.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.
- 9.A straight line is drawn from the centre of a circle to a point on the circle. Write down the name of this line.
- 10.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?
- 11.Write down the term for the distance all the way around the edge of a circle.
- 12.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.
- 13.A circle has a radius of 3 cm. Work out the diameter of the circle.
- 14.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.
- 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.
