Question

a gardener want to fencing a circular garden of diameter 42 metre find the length of the Rope he need to purchase if he make two rounds of pens in also the cost Rs 5 per metre ​

Answer 1

Step-by-step explanation:

Diameter = 42 m

radius = 21 m

Circumference of circular garden = 2πr

=2×22/7×21

=2×22×3

=44×3

=132m

132 m rope is required.

If he make two rounds the rope needed is 264 m.

Then the cost of fencing for one round is = Rs.5 × 132 = Rs.660

The cost of fencing of garden for two rounds is =Rs.5 × 264m = Rs.1320
