Question

the cost of fencing a circular field at the rate Rs 24per metre is Rs5280.The field to be ploughed at the rate of Rs 0.50per meter² .Find the cost of ploughing the field ( take π=22/7)​

Answer 1

Answer:

Rupees 1925

Step-by-step explanation:

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

For Rs. 5280, the length of fencing =   5280 = 220 metres.

Circumference of the field = 220 m

2pr =220

2x  r =220  

Area of the field =   r2 =   (35)2 =1225 m2

Cost of ploughing = Rs. 0.50 per m2

Total cost of ploughing the field = Rs. 1225  x 0.50

= Rs.  1925
