Question

17. The radius of a circular path is 7m. Find the cost of fencing the path if the cost per meter is Rs.35​

Answer 1

The cost of fencing the path is Rs 1539.38.

It is required to find the cost of  fencing the path.

What is circle?

A circle is a closed two-dimensional figure in which the set of all the points in the plane is equidistant from a given point called “centre”. The perimeter around the circle is known as the circumference.

Given that:

radius of a circular path is 7m.

Rate = Rs .35​ per meter

We know that

Circumference of circle =$2\pi r$

                                  $2*\pi *7\\\\=43.98 m$

Circumference of circle=43.98 m

Now,

Cost = Circumference × Rate

Cost =43.98× 35

Cost =  Rs 1539.38

Therefore, the cost of fencing the path is Rs 1539.38.
