Question

Find the cost of fencing a circular garden of radius 5.6 m if the rate of fencing is ₹13/m.

Answer 1

Circumference =2*22/7*5.6=35.2m
Cost of fencing = 13 * 35.2= Rs 457.6

Answer 2

We are given with radius of the circle which is 5.6 m and the rate of fencing at 13rs per meter

So, firstly we need to find the perimeter or the circumference of the given circle by its formula.


Therefore,        circumference of circle = 2(22/7)(5.6)
                                                                  = 44(0.8)
                                                                  = 35.2 m
Now, the cost of fencing per meter = 13rs
            => the cost of fencing on 35.2 m = 13(35.2)
                                                                    =457.6 rs (approx)
