diameter = 126m
radius =126/2 m
= 63m
width of path =6m
radius including path =69m
area of circle including path =π(69m) ^2
= 4761πm^2
area of circle excluding path = π(63m)^2
= 3969πm^2
area of path = 4761πm^2 - 3969πm^2
= 792πm^2
radius =126/2 m
= 63m
width of path =6m
radius including path =69m
area of circle including path =π(69m) ^2
= 4761πm^2
area of circle excluding path = π(63m)^2
= 3969πm^2
area of path = 4761πm^2 - 3969πm^2
= 792πm^2
