Please tell the answer of this question​

Answer 1

Answer:

Step-by-step explanation:

diameter of the circle = 63 m

radius of the circle = diameter / 2 = 31.5

circumference = 2*22/7*31.5

                        =  198 m

cost of fencing for 1 m  = 30 rupees

Cost of fencing for one round = 198*30

                                                  = 5940 rupees

Cost of fencing for four round = 5940*2

                                                  = 11880 rupees
