Find the total cost of wooden fencing around a circular garden of diameter 28 m, if 1m of fencing costs ₹300.

Solution:

It is given that

Diameter of a circular garden = 28 m

We know that

Length of fencing = Circumference of the circle

= π d

Substituting the values

= 22/7 × 28

= 88 m

As 1 m of fencing costs ₹300

Total cost of wooden fencing around a circular garden = 88 × 300

= ₹ 26400.

Therefore, the total cost of wooden fencing around a circular garden is ₹ 26400.
