Answer:
22000 Rs.
Step-by-step explanation:
Given:-
The distance between fountain and boundary of the park, which is also radius = 70 m.
Fencing rate per metre = 50 Rs.
Circumference = 2πr
= 2 × 22 × 70
____
7
= 2 × 22 × 10 = 440 m.
Therefore, circumference = 440 m.
Cost of fencing park = circumference × rate
= 440 × 50 = 22000 Rs.
Therefore, the cost of fencing park will be 22000 Rs.
