Question

2. Draw concentric circles for the following measurement of diameters.
Find out the width of each circular ring.
d = 6.4 cm and d = 11.6 cm.​

Answer 1

Answer:

Step 1 - Draw a circle with radius r=4.2 cm and name the centre as O.

Step 2- Taking O as the centre, draw another circle of radius R=6.8 cm.

Then, the figure results into concentric circles with radius 6.8 and 4.2 cm.

Then width of circular ring =R−r=6.8−4.2=2.6 cm
