Question

The cost of fencing a circular field at the rate of Rs.24 per metre is Rs. 5280.

Find the radius of the field.​

Answer 1

Answer:

radius=35m

Step-by-step explanation:

total cost = Rs. 5280

cost of fencing = Rs. 24

total length of field = total cost of fencing / cost of fencing perimeter

= 5280/24

= 220m

total length= circumference of circular field

= 220=2πr

= 2*22/7*r = 220

= 44*r/7 = 220

= r =220*7/44

therefore, r = 35m
