Q1 of 6 Page 93

Draw concentric circles for the following measurements of radii. Find out the width of each circular ring.

4 cm and 6 cm.

4cm and 6cm
Steps of construction:

Step 1: Draw a rough image and mark the given measurement.



Step 2: Take any point O and mark its as centre.



Step 3: With O as centre, draw a circle of radius OA = 4cm.



Step 4: With O as centre, draw a circle of radius OB = 6cm.



Thus, the concentric circle C1 and C2 are drawn.


Width of the circular ring = OB – OA


= 6 – 4


= 2cm
