Question

Draw a concertric circle =5cm and r=7.5cm. find out the width of each circular ring.​

Answer 1

Answer:

1.7 cm

Step-by-step explanation:

Step 1 - Draw a circle with radius 5.3 cm and name the centre as O.

Step 2- Taking O as the centre, draw another circle of radius 7 cm.

Then, the figure results into concentric circles with radius 7 and 5.3 cm.

Then width of circular ring =R−r=7−5.3=1.7 cm
