question_answer 2)

With the same centre O, draw two circles of radii 4 cm and 2.5 cm.

Answer:

                Here, to draw two circles of radii 4 cm and 2.5 cm with the same centre O, we use the following steps: Step I Open the compasses to take distance of 4 cm for the required radius of circle. Step II Mark a point with a sharp pencil for the centre of the circle and name it as O. Step III Place the pointer of the compasses on O. Step IV Turn the compasses slowly, to draw the circle of radius 4 cm. Step V Now, again open the compasses to take a distance of 2.5 cm for the required radius of circle. Step VI Place the pointer of the compasses on O (since, both circles have same centre). Step VII Turn the compasses slowly, to draw the circle of radius 2.5 cm. Thus, we get two circles with same centre O and radius 4 cm and 2.5 cm, respectively.
