given
diameter of park = 224cm
so radius = 112cm
width of road= 4cm
sol.
area of park = πr^2
= 22/7 *112*112
= 275968/7=39424cm^2
area of park including road = πr^2
radius of park including road= 112+4
= 116cm
so
area = 22/7*116*116
=296032/7
=42290.28cm^2
now
area of road= area of park including road-area of park
= 42290.28-39424
area of road = 2866.28 cm ^2
