Question

The formula to find the width of the circular path is

Answer 1

$\large\underline\purple{\bold{Solution :- }}$

• Let us consider a inner circle radius 'r'

and

• Let us consider an outer circle of radius 'R',

having same centres,

then

• Width (d) of a circular path is given by

$\longmapsto \: \rm \: d \: = \: outer \: radius \: - \: inner \: radius$

$\longmapsto \: \rm \: d \: = \: R \: - \: r$
