A circle has a circumference of 34 54 cm. What is the area of the circle to the nearest whole centimeter? Use 3.14

inysia [295]

Answer:

Step-by-step explanation:

We know that the Circumference = 3454 cm

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

$2\pi \times r$

So we can put the equation this way,

$3454 = 2\pi \times r$

So we can solve for 'r'

$3454 = 2 \times 3.14 \times r \\ 3454 = 6.28r \\ r = \frac{3454}{6.28} \\ r = 550$

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

$\pi \times {r}^{2}$

$3.14 \times 550 \times 550 \\ = 949850$

We can convert this to meter,

9498.5 m

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