Answer:
Circumference of a circular park = 352
m
Width of a road = 7m
Circumference rce = 2pi * r 352 = 2(22/7) * r
352 * 7 = 44r
r=(352*7)/44=8*7=56 m
Inner radius of the park (r) = 56m Outer radius of the Park including the road (R) = width + r
R = 7 + 56 = 63m
R = 63m
Area of the road = Pi(R ^ 2 - r ^ 2)
= Pi(R+r)(R-r)[a^ 2 -b^ 2 =(a-b)(a-b)]
=22/7(63+56)(63-56)
=22/7*119*7
=22*119
Area of the road = 2618m ^ 2
