of the outer edge of the footpath is 506 m. Find the width of the
footpath.​

Answer 1

Answer:

2.47m

Step-by-step explanation:

given,

length of outer edge of the footpath is 506m,

that means it is perimeter of the footpath around circular park,

i.e,2πr = 506,

=>r = 80.53 m,

given circular park diameter = 154m,i.e,r= 77m.

therefore width of the footpath is 80.53-77 = 2.47m
