Question

Find the total cost of wodden fencing around a circular garden of diameter 28m, if 1m of fencing costs ₹400.​
​

Answer 1

Area of circle = 22/7 * 14 * 14
22* 2 * 14 = 616 m square
Cost of fencing = 616 * 400
= 246400 rupees

Answer 2

Answer:

WE NEED TO FIND THE PERIMETER AS WE FENCE AROUND THE BOUNDARIES

Diameter=28m

Radius=Diameter/2=28/2=14m

Perimeter of circle=2πr

                              = 2*22/7 *14

                              =2*22*2

                              = 88m

Cost of 1m of fencing= ₹400

Cost of 88m of fencing= ₹400*88

Cost of fencing= ₹35200
