Two concentric circles form a ring. The inner and outer circumferences of ring are $ 518 7$ m and $ 352 7$ m respectively. Find the width of the ring.

ক) 4 — Let the inner and outer radii be r and R metres. Then $2 πR = 352 7=> R= 352 7 7 22 12=8 m$ $2 πR = 528 7=> R= 528 7 7 22 12=12 m$ => Width of the ring = (R - r) = (12 - 8) m = 4 m.

Explanation

Let the inner and outer radii be r and R metres. Then

2\mathrm{πR}=\frac{352}7=>\mathrm R=\frac{352}7\ast\frac7{22}\ast\frac12=8\mathrm m

2\mathrm{πR}=\frac{528}7=>\mathrm R=\frac{528}7\ast\frac7{22}\ast\frac12=12\mathrm m

=> Width of the ring = (R - r) = (12 - 8) m = 4 m.
