Q:

Two concentric circles form a ring. The inner and outer circumference of the ring are 352/7 m and 528/7m respectively.Find the width of the ring.

A) 5 B) 4
C) 3 D) 2
 
Answer & Explanation Answer: B) 4

Explanation:

let the inner and outer radii be r and R meters
then, 2πr = 352/7

 

=> r = (352/7) * (7/22) * (1/2) = 8m
2πR = 528/7

 

=> R= (528/7) * (7/22) * (1/2)= 12m
width of the ring = R-r = 12-8 = 4m
