Question

the radius of the circular Garden is 7 M the cost of fencing the garden at the rate of rupees 10 per metre will be​

Answer 1

Step-by-step explanation:

cost of fencing per meter = ₹10

radius of circular garden = 7m

so, 10×7 = 70 m ans

Answer 2

The cost of fencing the garden is Rs. 440.

Given,

The radius of the circular garden is 7 m.

To Find,

The cost of fencing the garden at the rate of rupees 10 per metre will be​ =?

Solution,

We can solve the question as follows:

It is given that the radius of the circular garden is 7 m. We have to find the cost of fencing the garden at the rate of rupees 10 per metre.

$Radius = 7\: m$

$Rate\: per\: metre = Rs.\: 10$

First, we will find the circumference of the garden.

The formula for finding the circumference of a circle is:

$Circumference =2\pi r$

Substituting r = 7 m in the above formula,

$Circumference = 2*\frac{22}{7} *7$        $(\pi = \frac{22}{7} )$

                         $= 2*22 = 44\: m$

Now,

The cost of fencing the garden will be equal to the circumference of the garden multiplied by the cost of fencing 1 metre.

Therefore,

$Cost\:of\: fencing\: the\: garden = Circumference*Rate\: per\: metre$

                                            $= 44*10 = Rs.\: 440$

Hence, the cost of fencing the garden is Rs. 440.
