Question

the radius of the park 63 m. find the cost of fencing it at $12 per metre.

Answer 1

Answer:

Step-by-step explanation:

Given radius of park (r) = 63 m

So, circumference of park = 2$\pi$r

= 2 × (22/7) × 63

= 396 m

Given rate of fencing = $ 12 / m

So, total cost of fencing = circumference × rate/m

= 396 × 12

= $ 4752

Answer 2

It would require $4752 for the fencing of park.

Step-by-step explanation:

We have,

Radius of the park is 63 m

It is required to find the cost of fencing the park at $12 per metre. For fencing, it means we need to find the outer covering of the park i.e. its circumference. So,

$C=2\pi r$

Putting r = 63 m

$C=2\times \dfrac{22}{7}\times 63\\\\C=396\ m$

At the rate of $12 per meter :

$\text{cost}=\ 396\cdot12=\ 4752$

So, it would require $4752 for the fencing of park.
