Answer:

9498.5 m

Step-by-step explanation:

We know that the Circumference = 3454 cm

And we also know that the formula for the Circumference of Circle is,

[tex]2\pi \times r[/tex]

So we can put the equation this way,

[tex]3454 = 2\pi \times r[/tex]

So we can solve for 'r'

[tex]3454 = 2 \times 3.14 \times r \\ 3454 = 6.28r \\ r = \frac{3454}{6.28} \\ r = 550[/tex]

Now we have radius and we can solve for the area of the circle,

[tex]\pi \times {r}^{2} [/tex]

[tex]3.14 \times 550 \times 550 \\ = 949850[/tex]

We can convert this to meter,

9498.5 m

I am not sure if this is correct just let me know thanks :)
