Question

A circular park of diameter 154m has a footpath around it. The length of the outer edge of the footpath is 506m.find the width of footpath.

Answer 1

Width of foot path =  3.5 m

Step-by-step explanation:

A circular park of diameter 154m

=> Radius  = 154/2 = 77 m

footpath around it

=> inner Radius of foot Path = 77 m

The length of the outer edge of the footpath is 506m

length of the outer edge of the footpath = Circumference of circle

2 * π * Outer radius of footpath  = 506

=> 2 (22/7) Outer radius of footpath  = 506

=> Outer radius of footpath  = 80.5 m

Width of foot path = 80.5 - 77  = 3.5 m

Width of foot path =  3.5 m
