Question

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

A. 95 cm B. 11 cm С 108 cm2 D 380 cm​

Answer 1

9498.5 m

Explanation:

We know that the Circumference = 3454 cm

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

`2\pi * r`

So we can put the equation this way,

`3454 = 2\pi * r`

So we can solve for 'r'

`3454 = 2 * 3.14 * r \\ 3454 = 6.28r \\ r = (3454)/(6.28) \\ r = 550`

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

`\pi * {r}^(2)`

`3.14 * 550 * 550 \\ = 949850`

We can convert this to meter,

9498.5 m

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