Question

a Gardner wants to fence a circular garden of diameter 28 . find the length of the rope he needs to purchase if he makes 3 rounds of fence. also find the cost of the rope is it costs 15th per meter​

Answer 1

Answer:

Cost fence = Rs 3960

Step-by-step explanation:

Given:

Diameter = 28m

Radius = 28/2 = 14m

Fence the circular ground so we find perimeter.

Circumference of Circle = $2\pi r$

                                        $=2*\frac{22}{7}*14$

                                        $=2*22*2$

                                        $=88 m$

1 round = 88m

3 round = 3 * 88m

              = 264 m

1m      = Rs 15

264m = Rs 264 * 15

          = Rs 3960
