Question

the cost of fencing a circular Field at the rate of 10rupeey per meter square is rupey880find the cost of ploughing this field at the rate of rupey10pe meter square​

Answer 1

Answer:

dolp0lablaasaa@=☆sr.m

Answer 2

For Rs.24, then length of fencing =1m

For Rs.52 so, the length of fencing

=

24

1

×5280=220meters

Circumference of the field =220m

2pr=220

Therefore r=

44

220×7

=35m

Area of the field =πr

2

π(35)

2

=1225

Cost of ploughing =Rs.0.50 per m

2

Total cost of ploughing the field =Rs.1225

=

7×2

1225×22×1

=Rs,1925.

Hence, the answer is 1925.

Cost of fencing at the rate of Rs.240 per meter=Rs.52800

Therefore,

Circumference=

240

52800

=220

Let r be the radius of the field

Therefore,

2πr=220

=>r=

2×22

220×7

=>r=35

Therefore,

Area of the field=πr

2

=

7

22

×35×35

=3850m

2

Cost of fencing the field=12.5×3850

=Rs.48125
