》To find :

Cost of fencing

》Given :

Radius = 7.7 meter

Rate = Rs 50 per meter

》Solution :

In order to find the cost if fencing we need to find the circumference of the plot and then multiply it with the rate.

So,

Circumference of circle = $2\pi r$

Circumference = $2\times\pi\times7.7$

Circumference = 48.4 meter

So, the circumference of the circular plot is 48.4 meter.

Now,

Cost = Circumference × Rate

Cost = $48.4\times 50$

Cost = Rs 2420

So, the cost of fencing will be Rs 2420.

Rate = Rs 50 per meter

》Solution :

In order to find the cost if fencing we need to find the circumference of the plot and then multiply it with the rate.

So,

Circumference of circle = 2\pi r2πr

Circumference = 2\times\pi\times7.72×π×7.7

Circumference = 48.4 meter

So, the circumference of the circular plot is 48.4 meter.

Now,

Cost = Circumference × Rate

Cost = 48.4\times 5048.4×50

Cost = Rs 2420

So, the cost of fencing will be Rs 2420.
