Answer:
cost of fencing a circular place of radius 7.7 m with three rounds of wire = 7260 Rs
Step-by-step explanation:
circular place of radius 7.7 m
Circumference of circle = 2πR
π = 22/7
r = Radius = 7.7 cm
Circumference = 2 * (22/7) * 7.7
= 48.4
three rounds of wire
=> Length of Wire required = 48.4 *3
= 145.2 m
Wire cost = Rs 50 per meter
Total Wire cost = 50 * 145.2
= 7260 Rs
cost of fencing a circular place of radius 7.7 m with three rounds of wire = 7260 Rs
