Question

the radius of a circular plot is 15.4 cm how much will it cost to fence the plot with 4 rounds of wire at the rate of 60trs per m​

Answer 1

Answer:

Step-by-step explanation:

Radius r = 15.4 cm

We have to fence it.Hence circumference is concerned.

Circumference=2πr=2*22/7*15.4=96.8cm

We have to fence it 4 times.so the wiring we have to do will be on 96.8*4 = 387.2cm=3.872m

Cost = 60/m=3.872*60=232.32 ruppess

Hope it helps
