Question

The cost of fencing a circular field at the rate of Rs.20 per metre is Rs. 5280. Find the radius of the field.​

Answer 1

Step-by-step explanation:

But given that the cost of fencing the field is Rs. 5280. r=528048π=4854π=35 metres. Hence the radius of the field is 35 metres.

Answer 2

Answer

5280 is rate for total fencing and 20 rupees for 1 meter

So, 264 meter is circumference of circular field

So, now

circumference = 2πr

264=2×22/7×r

264×7/44=r

42m=r
