Question

the cost of fencing a semicircular garden of radius 14 M at 10 rupees per metre is

Answer 1

circumference of semicircle is πr+2r

= 3.14*14+2*14

= 43.96+28

= 71.96 m

cost of fence is 10 Rs/m

cost of fence for 71.96m

= 71.96*10

= 719.6 Rs

Answer 2

The cost of fencing a semi circular garden is Rs. 720.

Step-by-step explanation:

Since we have given that

Radius = 14 m

We need to find the circumference of semi circle;

As we know that

$C=\pi r+2r\\\\C=\dfrac{22}{7}\times 14+2\times 14\\\\C=44+28=72\ m$

Cost per meter = Rs. 10

so, the cost of fencing would be

$72\times 10\\\\=Rs.\ 720$

Hence, the cost of fencing a semi circular garden is Rs. 720.
