Answer:

Ans = 7,920

Step-by-step explanation:

Circumference = 2 pay ( symbol ) r

Circumference = 2 × 22 7

----- ×

7

Both 7 will be cut...

= 2×22 = 44 m

Need to find the cost of fencing 4 rounds

= 4 × 44 = 176 m

Answer 2

Answer:

₹7920.

Step-by-step explanation:

Diameter (d) = 14m

We know,

$\pi = \frac{22}{7}$

So, Circumference of the circle

$= (\pi \: d )\: {unit}$

$= (\frac{22}{7} \times 14)m$

$= 44m$

The plot will be fenced with four rounds.

So, length of wire needed for four rounds

$= (44 \times 4)m$

$= 176m$

COST OF FENCING= ₹45 PER METRE

NOW, THE COST OF FENCING IS

$rupees \: (176 \times 45)$

$= rupees \: 7920$

THEREFORE , THE COST TO FENCH THE PLOT WITH FOUR ROUNDS OF WIRE IS ₹7,920 (ANSWER.)

HOPE IT HELPS.
