Question

a circular road runs round a circular gardan. if the circumference of the outer circle and the inner circle are 110m and 88m.find the width of the road

​

Answer 1

Let the outer and inner radii are k and r respectively.

Width of the road =R−r

Now 2πR−2πr=44m

⇒2π(R−r)=44

R−r= 44/2π

=7m
