- 1.A circle is drawn on a page. Write down how many radii can be drawn in the circle.
- 2.The curved part of a circle's circumference, between two points on the circle, has its own name. Write down this name.
- 3.A circle has a diameter of 4 cm. Work out the radius of the circle.
- 4.A chord is drawn across a circle, dividing the circle into two regions. Write down the name of one of these two regions.
- 5.A circle has circumference 31.4 cm. Using π = 3.14, work out the radius of the circle.
- 6.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.
- 7.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.
- 8.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.
- 9.A circular table mat has diameter 20 cm. Yasmin has a 70 cm length of ribbon and sews it around the edge of the mat with no overlap. Using π = 3.14, work out how much ribbon is left over after going around the mat once.
- 10.Every point on a circle is exactly the same distance from one particular point. Write down the name of that point.
- 11.Write down the term for the distance all the way around the edge of a circle.
- 12.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.
- 13.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.
- 14.A diameter divides a circle into two equal halves. Write down the special name given to each of these two halves.
- 15.A circle has a radius of 3 cm. Work out the diameter of the circle.
