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
