Question

The area of a circle is 3850 power 2 to find the circumference of it and also find cost of wire at rupees 2.40 per metre to fence it

Answer 1

Step-by-step explanation:

area of circle = 3850^2=pie×r^2

taking sq root on both sides

pie×r=3850

r=3850×7/22

r=1225m

circumference=2×pie×r

2×1225×22/7=7700 sq metre

cost of wire÷

7700×2.40=18480 rupees
