Step-by-step explanation:
since area of circular region exclude the path
= pi r² = 2464 => r²= 2464×7/22= 784 m²
radius (r)= 28 m.
since breadth of circular path= 1 m
radius with path = r+1 meter= 29m
therefore area of path=
area include- area exclude of path
= pi [ (r+1)²-r²]
=. pi[ 2r+1]
= 22× 57/7= 179.14 m²
total cost= 179.14× 1.85
= 331.40 rupees approximately
