<h3>What is circle?</h3>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 =
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.
