Practice Questions
Answer all questions. Show your working in the grid spaces provided.
1.
A circle has a radius of 7 cm. Calculate its diameter.
[2 marks]2.
If a diameter of a circle measures 18 cm, what is the radius of the circle?
[2 marks]3.
Construct a circle with a diameter of 10 cm on the grid. Label the diameter.
[3 marks]4.
A student claims that the diameter is always twice the length of the radius. Is this statement correct? Explain your answer.
[3 marks]5.
A circle's diameter is incorrectly measured as 16 cm when the radius is given as 8 cm. Identify and explain the mistake.
