Question

A gardener wants to fence a circular garden of 21m find the length of the
rope he needs to purchase, if he makes 2 round of fence.​

Answer 1

Answer:

Diameter of the circular garden=21m

::.Radius of the circular garden=

$\frac{21}{2}m$

Now, circumference of circular garden=

$2\pi \: r = 2 \times \frac{22}{7} \times \frac{21}{2}$

The gardener makes 2 rounds of fence so the total length of the rope of fencing=

2 x 2πr = 2 x 66 = 132m

Since the cost of 1 meter rope=Rs. 4

Therefore, cost of 132 meter rope= 4x

132 =Rs. 528.
