- 2.Every point on a circle is exactly the same distance from one particular point. Write down the name of that point.
- 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 chord divides a circle into two segments of different sizes. Write down the name given to the smaller of the two segments.
- 5.A circle has a diameter of 4 cm. 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 chord is drawn across a circle, dividing the circle into two regions. Write down the name of one of these two regions.
- 8.A circle has diameter 10 cm. Using π = 3.14, work out the circumference of the circle.
