Question

diameter of circular plot is 28 m what would it cost to put 3 rounds of wire around his plot at a rate of 50 rupees per metre.


Please answer me fast I do my homework yaar

Answer 1

Step-by-step explanation:

1. diameter is 28 so, circumference is 22/7*28 equals to 88 so three rounds 88*3equals to 264 . cost is 264*50 equals to 13200

Answer 2

Cost of fencing three rounds of wire is 13194.69 rupees.

• Diameter(d) of a circular plot is given as 28 m.
• Radius(r) of the circular plot will be $\frac{d}{2}$ = 14 m.
• We have to find the cost to put three rounds of wire around the plot.
• To put wire around the circular plot we need to calculate the circumference of the circular plot.
• Circumference of the circle is given by = 2πr

Circumference of the circular plot is 2π(14).

Circumference of the circular plot is 28π m.

• Now the rate of fencing wire is 50 rupees per metre.
• Therefore cost of fencing the circumference once will be

Cost = 50 × 28π

Cost = 4398.23 rupees.

• Now we have to fence 3 rounds will be

Total cost = 3 × 4398.23

Total cost = 13194.69 rupees
