  1. Answer :

    → Radius of circular park = D/2 = 86/2 = 43 m .

    so,

    → Cost of fencing the park = Rate * circumference = 11 * 2 * 3.14 * 43 = Rs. 2970.44 (Ans.)

    now,

    → Area of path = π[(43 + 4)² – (43)²] = 3.14(47² – 43²) = 3.14 * 90 * 4 = 1130.4 .

    then,

    → Cost of turfing the path = Rate * Area = 7.5 * 1130.4 = Rs.8478 (Ans.)
