Answer:
The cost of fencing will be Rs. 7260
Step-by-step explanation:
Here the radius of a circle is given to be 7.7 m
We will first find the circumference of the circle
circumference of circle = 2πr
= 2 × (22/7) × 7.7
= 44 × 1.1
= 48.4
fencing needed for 3 rounds = 3 × 48.4
= 145.2 m
cost of fencing = 145.2 × 50
= 7260
