Answer 2

Answer:

6.a 1320 m

6.b Rs 10560

Step-by-step explanation

6.a

Radius of circular field=42m

So perimeter of the circular field=2πr

                                                     =2*22/7*42 m

                                                     =264m

1 round around the circle=Perimeter

So 5 rounds around the circle=5*Perimeter

                                                 =5*264 m

                                                 =1320 m

Ans:- So length of fence is 1320 m

6.b

Diameter of circular pond=70 m

So radius=1/2*70 m=70/2 m

Perimeter of the circular pond=2πr

                                                 =2*22/7*70/2 m

                                                 =220 m

Fencing it 4 times= 4* perimeter

                             = 4*220 m

                             = 880 m

Cost of fencing per metre=Rs 12

So cost of fencing 880 m=Rs 12*880

                                          =Rs 10560

Ans:- Cost of fencing four times is Rs 10560
