Question

Draw concentric circles for the following measurements of radii / diameters. Find out the width of the circular ring. r = 3 cm and r = 5 cm.​​

Answer 1

Answer:

(i) r = 3 cm and r = 5 cm.

(ii) r = 3.5 cm and r = 6.5 cm.

(iii) d = 6.4 cm and d = 11.6 cm.

(iv) r = 5 cm and r = 7.5 cm.

(v) r = 7.1 cm and d = 12 cm.

(vi) r = 7.1 cm and d = 12 cm.
