Answer:
20.02m^2
Step-by-step explanation:
Let the radius of the circular park be r
Therefore,
2πr=55
=>r=
2×22
55×7
=>r=8.75
Area of the circular park =
7
22
(8.75)
2
=240.63m
2
Width of the park =0.35m
Area of the circular park with the uniform path=π(r+0.35)
2
=
7
22
(8.75+0.35)
2
=260.65m
2
Area of the uniform path =(260.65−240.63)m
2
=20.02m
