Question

Please answer its urgent

Answer 1

radius of circular field = 105 m
width of path is 5m
then area of total circular region will be pi r^2
where r is 105 + 5 = 110 m
= 22/7×110 × 110
=266,200 / 7
= 38028.5 m2 (approx)

now area of circular field is pi r^2
= 22/7 × 105 ×105
= 242,550/7
= 3465 m2

now area of path will be area for total region - area of circular field
= 38028.5 - 3465
= 3378.5 m2
