Question

the radius of a circular Park is 56 metre find thecost of wire required to fence twice around the circular Park at the rate of rupees 3.85 per metre ​

Answer 1

Answer:

2710.4 rupees

Step-by-step explanation:

Radius of the park = 56 metres

Fence around the circular park means circumference

Circumference of circle = 2pi *r

Circumference = 2*22/7*56

Circumference = 352m

As it has to be fenced twice,

2×352= 704m

Cost = 704*3.85 = 2710.4 rupees

The cost will be 2710.4 rupees

Answer 2

AnswEr :

• Radius of Park = 56 m
• Rate of Fencing = Rs. 3.85 @metre
• Find Cost of Fencing twice around.

⋆ Refrence of Image is in the Diagram :

$\setlength{\unitlength}{1cm}\thicklines\begin{picture}(8,10)\put(5,10){\line(1,0){0.7}}\put(5.1,10.1){\scriptsize{ 56m }}\put(5,10){\circle{10}}\end{picture}$

• Let's Head to the Question Now :

$\longrightarrow \tt Circumference = 2\pi r \\ \\\longrightarrow \tt Circumference = 2 \times \dfrac{22}{ \cancel{7}}\times\cancel{56 \:m} \\ \\\longrightarrow \tt Circumference =2 \times 22 \times 8 \:m \\ \\\longrightarrow \tt Circumference =352 \:m$

$\rule{300}{1}$

• According to the Question Now :

$\implies \tt Total\:Cost = 2(Circumference) \times Rate \\ \\\implies \tt Total\:Cost = 2(352) \times 3.85 \\ \\\implies \tt Total\:Cost = 704 \times \frac{385}{100} \\ \\\implies \tt Total\:Cost = \dfrac{271040}{100} \\ \\\implies \boxed{ \orange{\tt Total\:Cost = Rs. \:2710.40}}$

⠀

∴ Cost of Fencing twice is Rs. 2710.40
