Question

There is a wide track around the circular park. Difference between the circumference

of the track and that of circle is 132 meters. Then the width of the track is …… m a)

30 b) 40 c) 50 d) 21​

Answer 1

Answer:

d)21

Step-by-step explanation:

Given, circumference of the outer circle(track) =132m

Let, the radius of the outer circle be R meters and inner circle be r meters.

Therefore,

R-r=(132*7)/(2*22)

or,R-r=3*7 [after cancelling 132/2*22]

or, R-r=21

Therefore width of the Track is 21 meters.
