Answer :

Given,


Diameter of circular pond = 17.5m


Radius of circular pond = = 8.75m


Radius of outer circle = (radius of inner circle + width of circular path)


= 8.75+2 = 10.25m


Area of circular path = (area of outer circle – area of inner circle)


= π(R2 – r2)


= π(R+r)(R-r)


= (10.75+8.75)(10.75-8.75)


= × 19.50 × 2 = 3061.50 m2
