Question

2. Draw a circle of radius$\mathbf{3}\mathbf{.}\mathbf{0}\mathbf{}\mathit{c}\mathit{m}$. Draw the chord AB of the circle passing through the centre of the circle. Now answer the following question.

(iii) What are the two circular regions in which AB divides the circle?

Answer 1

Required figure:

As we know that chord $AB$ is the diameter of the circle as it is passing through the centre.

The diameter divides the circle into two equal halves i.e. Semicircle. So the regions are known as Semi-circular regions.

The name of the two circular regions in which $AB$divides the circle is Semi-circular Regions.
